Les représentations de Tullie au XVIIIe siècle : au carrefour des genres
Authors: Gladu Kim 
Published: March 2023

Le personnage de Tullie, fille de Cicéron, a été représenté par plusieurs auteur·trices au XVIIIe siècle, en vertu d’un engouement qui tient sans doute autant à l’estime dont jouit le souvenir de son père qu’à un phénomène de mode selon lequel on s’intéresse aux femmes illustres de l’Antiquité. Ce sont les différentes modalités de ces représentations et de leur mise en discours qui ont retenu notre attention, dans une étude qui prend plus précisément pour objets trois oeuvres où intervient le personnage de Tullie : le roman de la marquise de Lassay, Histoire de Tullie, fille de Cicéron (1726), la tragédie Catilina (1748) de Crébillon père et enfin, le dialogue des morts de Voltaire intitulé « Les Anciens et les Modernes ou la toilette de Mme de Pompadour » (1761). Nous verrons en quoi la représentation du personnage et sa prise de parole sont tributaires de contingences liées au genre littéraire auquel appartient l’oeuvre, dans une perspective à la fois générique et dialogique.

Transient, collision-induced changes in polarizability for atoms interacting with linear, centrosymmetric molecules at long range
Authors: Hunt K. L. C. , Liang Y. Q. , Sethuraman S. 
Published: July 2002

Transient changes in polarizability during collisions between atoms and molecules give rise to interaction-induced rototranslational Raman scattering: the scalar component of the collision-induced polarizability Δα00 accounts for isotropic scattering, while the second-rank component ΔαM2 accounts for collision-induced depolarized scattering. We have evaluated the changes in electronic polarizability due to interactions between an atom and a molecule of D∞h symmetry in fixed configurations, with nonoverlapping charge distributions. We have cast the resulting expressions into the symmetry-adapted form used in spectroscopic line shape analyses. Our results are complete to order R−6 in the atom–molecule separation R. To this order, the collision-induced change in polarizability of an atom and a D∞h molecule reflects not only dipole-induced–dipole (DID) interactions, but also molecular polarization due to the nonuniformity of the local field, polarization of the atom in the field due to higher multipoles induced in the molecule, hyperpolarization of the atom by the applied field and the quadrupolar field of the molecule, and dispersion. We have analyzed the dispersion contributions to the atom–molecule polarizability within our reaction-field model, which yields accurate integral expressions for the polarizability coefficients. For numerical work, we have also developed approximations in terms of static polarizabilities, γ hyperpolarizabilities, and dispersion energy coefficients. Estimated polarizability coefficients are tabulated for H, He, Ne, and Ar atoms interacting with H2 or N2 molecules. The mean change in polarizability Δᾱ, averaged over the orientations of the molecular axis and the vector between atomic and molecular centers, is determined by second-order DID interactions and dispersion. For the lighter pairs, dispersion terms are larger than second-order DID terms in Δᾱ. In both Δα00 and ΔαM2, first-order DID interactions dominate at long range; other interaction effects are smaller, but detectable. At long range, the largest deviations from the first-order DID results for Δα00 are
produced by dispersion terms for lighter species considered here and by second-order DID terms for the heavier species; in ΔαM2, the largest deviations from first-order DID results stem from the effects of field nonuniformity and higher multipole induction, for atoms interacting with N2.

Optical–optical double-resonance excitation together with electron spectroscopy was used to measure the H+2 rotational state distributions produced by vibrational autoionization of singlet np Rydberg states of H2 . In the two-color excitation scheme, one laser was used to excite the two-photon transition to the H2 E, F 1∑+g, v′=1, J′=1 state, and a second laser was used to probe single-photon transitions to the vibrationally autoionized np Rydberg series converging to the X 2∑+g, v+=1, N̄+=1 and N̄+=3 levels of the ion. The expected P(1)npσ, Q(1)npπ, R(1)np1, and R(1)np3 Rydberg series converging to v+ =1 were observed and assigned, as were several interlopers converging to higher vibrational levels of the ion. Rotationally resolved photoelectron spectra were determined for all of the autoionizing transitions by using a magnetic bottle electron spectrometer. Under the normal assumptions that p waves are ejected and that spin effects are negligible, vibrational autoionization of the upper levels of the P(1)npσ and Q(1)npπ transitions should produce only v+ =0, N̄+ =1, while vibrational autoionization of the upper levels of the R(1)np1 and R(1)np3 transitions should produce a mixture of v+ =0, N̄+ =1 and v+ =0, N̄+ =3. Significant deviations from these expectations were observed. For example, vibrational autoionization of the upper levels of the Q(1)npπ transitions produced substantial amounts of v+ =0, N̄+ =3, while vibrational autoionization of the upper levels of certain Q(1)npπ, R(1)np1, and interloper transitions produced nonnegligible amounts of v+ =0, N̄+ =5. This indicates that vibrational autoionization of npπ Rydberg states is accompanied by rotational state changes in the H+2 core to an unexpected degree, and that additional mechanisms for exchange of angular momentum within the excited complex must be considered. Possible contributing
mechanisms are critically assessed.
Intramolecular vibrational energy relaxation seen as expansion in phase space. I. Some experimental results for H2O+(X̃ 2B1), C2H+4(X̃ 2B3), and HCN+(B̃ 2∑+)

It has been shown by Heller that a nonstationary wave packet resulting from a Franck–Condon transition evolves on the potential energy surface of the final electronic state and propagates through phase space at a rate which can be determined from the autocorrelation function ↓C(t)↓2=↓〈(0)‖(t)〉↓2. Since C(t) can be obtained by Fourier transformation of an optical spectrum S(E), i.e., from an observable quantity, it is possible to derive from an experimental measurement information concerning the density operator of a so-called dynamical statistical ensemble (DSE). This density operator, denoted ρav, represents a statistical mixture of the eigenstates of the system with weights determined by the dynamics of the system. It becomes diagonal after a so-called break time 𝒯B. Its measure, according to a definition due to Stechel, can be interpreted as an effective number of states (denoted 𝒩) that significantly contribute to the dynamics. The break time 𝒯B represents the finite period of time allowed to expand in the phase space and after which no further progress can be made. Therefore, the number 𝒩∞ of phase space cells which are accessed after a very long interval of time (or in practice after the break time) remains limited.
Information on the validity of statistical theories of unimolecular reactions is contained in the fraction ℱ of the available phase space which is eventually explored. In order to assess the representativity of the sampling, it is necessary to account for the selection rule which requires all the states counted in 𝒩∞ to belong to the totally symmetric representation. It is also appropriate to estimate the role played by Fermi resonances and similar vibrational interactions which bring about energy flow into zero-order antisymmetric modes. A method to carry out the necessary partitionings is suggested. The functions 𝒩T and ℛT, and the quantities 𝒯B, 𝒩∞, 𝒩 *, and ℱ have been determined from experimental data in three cases. In each case, the rate ℛT=d𝒩T/dT starts from an initial value of zero, increases up to a maximum which is reached after a time of the order of 10−14 s, and then exhibits an overall decrease upon which oscillations are superimposed. For state X̃ 2B1 of H2O+, 𝒯B≂2.4×10−14 s and ℱ≂0.3. The wave packet never accesses that part of the phase space that corresponds to the excitation of antisymmetric vibrations. For state X̃ 2B3u of C2H+4, 𝒯B≂1.6×10−13 s and ℱ≂5×10−4. This fraction raises to 6×10−3 if measured with respect to the effectively available phase space. When the spectrum consists of a discrete part followed by a dissociation continuum, the method can be extended to study the behavior of the bound part of the wave packet only. This has been applied to state B̃ 2∑+ of HCN+ which is characterized by a very irregular spectrum. This case offers an example of complete occupation of phase space after a break time which is of the order of 2×10−13 s.
Dynamical processes in organic glassforming van der Waals liquids
Authors: Meier G. , Gerharz B. , Boese D. , Fischer E. W. 
Published: July 2002

This report presents measurements of the frequency dependent dielectric loss ε″(ω) and quasielastic light scattering of thermal density fluctuations of simple organic glassforming van der Waals liquids BCDE (bis-phenol-C-dimethylether) and BKDE (bis-kresol-C-dimethylether) having glass transition temperatures of Tg=240 K and Tg=261 K, respectively. The dielectric measurements of BCDE were carried out in a temperature range between 250 and 316 K, those of BKDE between 270 and 384 K covering a frequency range from 10−1 to ∼109 Hz in each case. Quasielastic light scattering data were taken between the glass transition temperatures and T≂Tg+30 K in a correlation time window of 10−6 s up to 102 s. As main results we have found the following: The relaxation process in the BCDE melt can be described using a Kohlrausch–Williams–Watts (KWW) function with a temperature independent β parameter. Its value was found to be identical either from the light scattering result or from the stretched exponential fit to the Fourier transform of the dielectric loss data.
The temperature dependence of the mean relaxation times of the BCDE melt was fitted with a Williams–Landel–Ferry (WLF) equation, or Vogel–Fulcher–Tammann equation, leading to WLF constants close to the universal ones. The BKDE system, however, behaves differently, where the dynamic response in the bulk amorphous state could only be described using a temperature dependent β parameter. This finding was confirmed by either the light scattering method as well as the dielectric relaxation method. Additionally we were able to measure a second dielectrically active process in BCDE only, arising in the high frequency region with an Arrhenius type of activation energy. In the BKDE melt, however, the superposition of different processes causes a temperature dependence of the β parameter when the data is forcefitted with a single KWW function. To correlate the fast process of BCDE (β process) with a possible molecular model of motion we have performed additional 2H-NMR solid echo measurements on both materials around and well below Tg. Thereby a 180° phenyl ring flip motion in BCDE was found in contrast to BKDE. This assignment of the secondary relaxation process is discussed together with the results from other methods.
Time correlation function approach to vibrational energy relaxation in liquids: Revised results for monatomic solvents and a comparison with the isolated binary collision model
Authors: Adelman S. A. , Muralidhar R. , Stote R. H. 
Published: July 2002

A refined version of a molecular theory of liquid phase vibrational energy relaxation (VER) [S. A. Adelman and R. H. Stote, J. Chem. Phys. 88, 4397, 4415 (1988)] is presented and compared to the isolated binary collision (IBC) model. The theory is based on the Gaussian model for the fluctuating force autocorrelation function of the solute vibrational coordinate. Within the Gaussian model, the VER rate constant may be constructed in terms of solute–solvent site–site potential energy and equilibrium pair correlation functions. In the present refined treatment, crossfrictional contributions to the fluctuating force autocorrelation function are retained and its initial value 〈F̃2〉0 is evaluated from an exact rather than an approximate formula. Applications of the theory are made to model Lennard-Jones systems designed to simulate molecular iodine dissolved in liquid xenon at T=298 K and molecular bromine dissolved in liquid argon at T=295 K and T=1500 K. The refinements, along with an improved polynomial fitting procedure for the solute–solvent pair correlation functions, are found to yield significant changes in both the absolute VER rates and in their isothermal density dependencies.
Moreover, it is found for all three solutions that the Gaussian decay time is nearly independent of density from ideal gas to the dense fluid regimes. This condition is sufficient for the emergence of an IBC-like factorization of the VER rate constant kliq(T) into a liquid phase structural contribution proportional to 〈F̃2〉0 and a dynamical contribution which is nearly density independent. The liquid structural contribution is, in general, not well-approximated by a contact collisional assumption but rather depends on a range of solute–solvent interatomic separations. For the Br2/Ar solutions, the rate constant isotherms show a superlinear deviation from the low density extrapolation kliq(T)≂ρ0kgas(T) which is qualitatively similar to that observed for a number of cryogenic and pressurized fluids. For the I2/Xe solution a qualitatively different sublinear rate isotherm is found. This ‘‘nonclassical’’ isotherm is correlated with the nonmonotonic density dependence of the magnitudes of the solute–solvent pair correlation function in the region important for the determination of 〈F̃2〉0 found for the I2/Xe system.
Comparisons of statistical and nonstatistical behavior for bond fission reactions in 1,2-difluoroethane, disilane, and the 2-chloroethyl radical

Published: July 2002

The unimolecular dissociation reactions of the 2-chloroethyl radical involving C–H and C–Cl bond fissions are investigated using classical trajectories and two variational transition-state theory methods on the same potential-energy surface. The transition-state theory methods employed are the efficient microcanonical sampling-transition state theory method, previously used to study the decomposition dynamics of disilane and 1,2-difluoroethane, and a J-conserving variant of this method that introduces constraining equations in the efficient microcanonical sampling procedure, such that the sampling is restricted to phase-space points associated with both a constant value of the system energy and total angular momentum.
The results demonstrate that the unimolecular dissociation of the 2-chloroethyl radical is well described by statistical theories that assume an equal weight for all energetically accessible phase-space points. The results obtained from the statistical calculations form upper bounds to the trajectory-computed rate coefficients as expected for a statistical system. In addition, there is no evidence of mode-specific dynamics present in the trajectory results. The statistical behavior of the 2-chloroethyl radical stands in sharp contrast to the dissociation dynamics of disilane and 1,2-difluoroethane which have previously been shown to exhibit pronounced nonstatistical effects. It is shown that the existence of nonstatistical behavior cannot, in general, be qualitatively predicted from energy considerations alone.
Comparison of the 2-chloroethyl radical, 1,2-difluoroethane, and disilane results again demonstrates that the existence of an energy decay rate out of a given bond that is fast relative to the unimolecular reaction rate is not a sufficient condition to guarantee statistical dynamics. It is found that the statistical behavior observed for 2-chloroethyl is due, in large part, to an increase in the potential coupling between the dissociating atom and the beta-carbon that occurs as the bond breaks. This coupling is associated with the conversion of the C–C single bond to a C■C double bond upon C–Cl or C–H bond fission in 2-chloroethyl. It is concluded that unimolecular reactions will tend to exhibit nonstatistical dynamics if (1) the internal energy is close to the dissociation threshold, (2) motion along the reaction coordinate does not produce large energetic changes in one of more bonds in the remainder of the molecule, and (3) there exists a formation coordinate for the activated reactant that is strongly coupled to the dissociation coordinate but only weakly coupled to the other internal coordinates of the molecule.
Dynamics of the reaction of O− with H2O : Reactive and nonreactive decay of collision complexes
Authors: Varley D. F. , Levandier D. J. , Farrar J. M. 
Published: July 2002

We present a study of reactive and nonreactive collisions between O− and H2O over the collision energy range from 0.67 to 1.07 eV. Kinetic energy analysis of the O− scattered nonreactively from H2O shows two components: The first arises from direct scattering and is nearly quasielastic, while the second occurs at significantly lower barycentric energies and corresponds to O− ejected without reaction from electrostatically bound O−⋅H2O complexes formed by approaching reagents. This latter flux is significantly more intense than the reactive OH− flux. The kinetic energy distributions for the low energy O− nonreactive flux are in qualitative agreement with statistical phase space theory, although recoil distributions that model the exit channel by an r −4 potential underestimate the kinetic energy release.
The reactive flux distributions show a strong energy dependence. At the lowest collision energy, the OH− is produced through two pathways, the first involving the participation of a complex living a fraction of a rotational period, the second producing OH− strongly backward scattered and with a much broader kinetic energy distribution. With increasing collision energy, the complex contribution to the scattering falls off rapidly, and product formation moves from the backward hemisphere to the forward direction. The angular distribution asymmetries at the lowest collision energies can be interpreted in terms of the osculating model for chemical reactions taking place in a fraction of a rotational period of the intermediate complex. This model suggests that the complex lifetime is ∼250 fs at collision energies between 0.7 and 0.8 eV, a result in good agreement with Rice–Ramsperger–Kassel–Marcus (RRKM) calculations. The kinetic energy distributions at these energies are in good agreement with statistical phase space theory calculations. At the highest collision energies, still below the threshold for impulsive stripping collisions, the OH− product is scattered sharply forward with a broad kinetic energy distribution peaking near 0.3 eV. We interpret the high energy dynamics as direct, but still involving significant interaction among all four atoms. The rapid variation in dynamics over a narrow collision energy range is attributed to the heavy–light–heavy mass combination of this system.
