Authors: Xiaoming Xiao , Matsumura-Inoue Takeko , Mizutani Shigeo 
Published: June 2004

Abstract
The 99Ru-NMR spectra of a series of tris-polypyridine ruthenium(II) complexes were studied in acetonitrile solution. The spectroscopic results indicate that the 99Ru-NMR chemical shifts of these complexes are sensitive to the environment around the metal center. The correlation between the 99Ru-NMR chemical shifts and the energy of metal-to-ligand charge transfer, EMLCT, was discussed.
Mechanism of Dye Bleaching upon Laser Excitation of Crystal Violet Bound to Bovine Serum Albumin
Authors: Indig Guilherme L 
Published: June 2004

Abstract
The laser induced photobleaching of crystal violet non-covalently bound to bovine serum albumin yields leuco crystal violet and Michler’s ketone as reaction products. The first step of the bleaching process is postulated to be an electron or hydrogen atom transfer from the protein to the dye moiety.

Thermochromism of Polysilanes Bearing Non-Ionic Polar Side Chains and Some LiClO4 Salt
Authors: Oka Kunio , Fujiue Naofumi , Nakanishi Saburo , Takata Toshikazu , Dohmaru Takaaki , Yuan Chien-Hua , West Robert 
Published: June 2004

Abstract
The titled polysilanes, {CH3-O(CH2CH2O)n-CH2CH2CH2-Si-CH3}x (n = 1∼3), are thermochromic both in the solid state and in solution. In the solid state these polysilanes all show a continuous bathochromic shift until nearly the same kink point temperature(190 K), then blue shift slightly. A water-soluble polysilane, n = 3, forms a complex with LiClO4. The thermochromic behavior of the complex is highly dependent on Li content. The complex of higher Li content shows only a blue shift on cooling while complexes of low Li content display red shift initially till Tg and then blue shift. An unexpected hyperchromic effect accompanied by the blue shift observed for the complex of Si:Li = 1:1 on cooling.

Electric Birefringence of Na-Montmorillonite Suspended in Water-Ethanol Mixed Solvent
Authors: Sasai Ryo , Gekko Kunihiko , Yamaoka Kiwamu 
Published: June 2004

Abstract
In order to clarify the effect of ethanol on the electrooptic and hydrodynamic properties of Na-montmorillonite (Na-M), the transient and steady-state electric birefringence (EB) of Na-M was measured in the water-ethanol mixed solvent system at a low particle concentration and at various ethanol contents. The hydrodynamic size of Na-M was decreased at ca. 10 vol% in EtOH content. This first EB attempt strongly supports the notion that the Na-M layers are delaminated by the adsorption of EtOH molecules onto the Na-M disk.

Effect of HOMO Levels on Chemiionization of Substituted Ethylenes by Metastable Helium Atoms
Authors: Yamakado Hideo , Okamura Kohji , Ohshimo Keijiro , Kishimoto Naoki , Ohno Koichi 
Published: June 2004

Abstract
Chemiionization reactivity (Penning ionization cross section) of substituted ethylenes in collision with helium metastable atoms was studied by velocity-resolved Penning ionization electron spectroscopy. Collision energy dependences of ionization probabilities of π orbitals were found to correlate with the HOMO levels. The higher the HOMO levels, the more effectively the reactive site of the ethylenes is hit by metastable atoms because of increased attractive interactions.
Kinetic Isotope Effects for Addition of Lithium Pinacolone Enolate to Benzaldehyde
Authors: Yamataka Hiroshi , Sasaki Daizo , Kuwatani Yoshiyuki , Mishima Masaaki , Tsuno Yuho 
Published: June 2004

Abstract
The carbonyl-carbon-13 and phenyl-D5 kinetic isotope effects (KIEs) were measured for the reaction of benzaldehyde and lithium pinacolone enolate. The KIEs together with ab initio MO calculations indicated that a CC bond formation process is involved in the rate-determining transition state of the reaction. It was concluded that the enolate addition reaction proceeds in a different manner from those for MeLi and PhLi, for which the rate-determining step was judged to be an electron transfer step.

Published: June 2004

Abstract
The electronic states of cobalt iron cyanides were observed using 57Fe Mössbauer. It was revealed that Prussian blue analogs Co1.5[Fe(CN)6]6H2O and K0.5Co1.25[Fe(CN)6]3.6H2O have FeIII(low spin) and FeII(low spin), respectively, at both room temperature and 4 K. In Co1.5[Fe(CN)6]6H2O, a magnetic hyperfine interaction was observed at low temperature. Moreover, the Mössbauer spectra provided clear evidence for an internal electron transfer from FeII to CoIII in K0.5Co1.25[Fe(CN)6]3.6H2O by red light illumination at low temperature.

Published: June 2004

Abstract
In a low temperature 29Si NMR spectrum measurement of 9,10-dimethyl-9,10-disilaanthracene dilithium (1), 29Si-7Li scalar coupling was observed. The 7Li NMR spectrum showed the two different environments for these two lithium atoms in 1 at 168 K. The spectral analysis strongly suggests a structure which has singly bridged lithium for two silicon atoms (1d).

Photoeffects on Electrorheological Properties of TiO2 Particle Suspensions
Authors: Rao Tata Narasinga , Komoda Yasuo , Sakai Nobuyuki , Fujishima Akira 
Published: June 2004

Abstract
The electrorheological (ER) effect of TiO2/silicone oil fluids was investigated under illumination. Two types of commercial TiO2 powders showed opposite photoeffects on the ER properties. While the photoinduced increase in the ER effect for the first type arises from the polarization of photogenerated charges, the decrease in the effect of the latter type appears to be due to photoelectrophoresis, which may be facilitated by effects associated with the large surface area and high water content.

VO(pic)2-NaY has been shown to retain solution like activity in oxidation of alkanes, alcohols and benzene with hydrogen peroxide.
Tribo- and Thermo-Luminescence of Aromatic Aldehydes
Authors: Koyanagi Motohiko 
Published: June 2004

Abstract
We found that two typical aromatic aldehydes, 2-furaldehyde and benzaldehyde, sometimes exhibit triboluminescence when these fluid materials at room temperature undergo phase transitions from their glassy phase to crystalline phases under a reduced pressure at low temperature, e. g., at 77 K. Several optical features thereof have been reported in the present paper. We also often observed characteristic thermal luminescence for a good few 2-furaldehyde solids which were subjected to large and frequent triboluminescence processes.
