### Vapor Pressures and Sublimation Enthalpy of 5 Mi  
The vapor pressures of crystalline 5 MI were measured using a mass-loss Knudsen effusion method. The equipment is prepared for the simultaneous use of nine effusion cells assembled in three series (\"Small\"--series A; \"Medium\"--series B; \"Large\"--series C); Details about the areas and the transmission probability factors of the effusion orifics are presented in Table S6. The corresponding experimental results obtained from each effusion cell are presented in Table S7. For the series of effusion orifics, Table 5 presents the detailed parameters of the Clausius-Clapeyron equation, \(\ln(p/\rm Pa)\;=\;a-b\;(K/T)\), where \(a\) is a constant and \(b\;=\;\Delta^{\rm g}_{\rm cr}H^{{}^{\circ}}_{\rm m}(<T>)/R\); the standard molar enthalpies of sublimation at the mean temperature \(<\)\(T\)\(>\) of the experiments are \(\Delta^{\rm g}_{\rm cr}H^{{}^{\circ}}_{\rm m}(<T>)\), and the entropy of sublimation at the equilibrium pressure for \(T\) = \(<\)\(T\)\(>\) is \(\Delta^{\rm g}_{\rm cr}S_{\rm m}\{(<T>),\,p(<T>)\}\). The plot of \(\ln p\) =\(f(1/T)\) for 5 MI is presented in Figure 2.  
The standard molar enthalpy of sublimation at \(T\) = 298.15 K was derived from the sublimation enthalpy calculated at the mean temperature of the experiments, using Equation (6), where \(\Delta^{\rm g}_{\rm cr}C^{{}^{\circ}}_{p,\rm m}\) is the difference between the molar heat capacities at constant pressure, between the gas and crystal phases. The value of \(\Delta^{\rm g}_{\rm cr}C^{{}^{\circ}}_{p,\rm m}\)(298.15 K) was calculated using Equation (7) developed by [PERSON] et al. [29], which is a rearrangement of an equation proposed by [PERSON] et al. [30]. \[\Delta^{\rm g}_{\rm cr}H^{{}^{\circ}}_{\rm m}(298.15\;\rm K)\;=\;\Delta^{\rm g }_{\rm cr}H^{{}^{\circ}}_{\rm m}(<T>)+\Delta^{\rm g}_{\rm cr}C^{{}^{\circ}}_{ p,\rm m}(298.15\;\rm K\;-\langle T\rangle) \tag{6}\] \begin{table}
