Abstract
The linear rates of sublimation of rhombic benzene and rhombic sulfur have been calculated by use of absolute reaction rate theory in reasonable agreement with rates derived from published experimental data. Required mean torsional oscillation and translational oscillation frequencies for the molecules in the crystal lattice were obtained by an analysis of the available heat capacity and Raman spectral data. A detailed comparison of this treatment with Penner's treatment of the sublimation process is included.Keywords
