## 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
