- Spectroscopic studies of phase transitions in some organic crystals: C $_2$H $_2$, CHBr $_3$ and CH $_3$CN
- Abstract
- Raman and infrared spectra of crystalline acetylene, bromoform and acetonitrile have been obtained. These three crystals and their fully deuterated analogues exhibit solid state phase transitions. Particular attention is given to the low frequency region (< 350 cm $^-1$) where lattice vibrations and low-lying intramolecular fundamentals are observed. Such properties as frequency shifts on deuteration, relative intensities and moment of inertia values are used to aid in assignments. Changes in the observed spectra for crystals below and above the transition temperature are related to the types of transition involved, and, where possible, comparisons are made with inorganic crystals having similar structures.
