✦ Synopsis

The Raman spectrum of the phenanthrene crystal HZ investigated between -190 and +90Β°C The ~sults indicate that intermolecular forces play an important role in the solid-solid phase transition at 7O'C. The assumption of a molecular conformational change was not confumed.

## Abstract Raman phonon spectroscopy in the 10–150 cm^βˆ’1^ shift range was used to study the phase transition in an __o__‐aminobenzoic acid crystal (II). At 77 K, twelve distinct phonon modes are observed whereas at 300 K the spectrum shows ten phonon bands. The temperature dependence of the phonon

The gypsum-bassanite-anhydrite phase transition sequence was followed up to 550 K at ambient pressure in a naturally occurring gypsum using Raman spectroscopy. The spectral variations of the internal (CaSO 4 AE 2H 2 O) modes of sulphate tetrahedra and were used to probe the structural phase transiti
