Raman frequencies calculated at various pressures in phase I of benzene
(KCS Publications, 2013)
We calculate in this study the pressure dependence of the frequencies for the Raman modes of A (Ag), B (Ag, B2g) and C (B1g, B3g) at constant temperatures of 274 and 294K (room temperature) for the solid phase I of benzene. ...
Calculation of the soft-mode frequency for the alpha – beta transition in quartz
The ? – ß structural transition occurs in quartz at TC = 846 K. The frequency of the soft mode associated with the volume increase, decreases with increasing temperature as the transition temperature is approached. In this ...
