Abstract

Raman phonon spectroscopy in the 10–170 cm−1 range has been used to study phase transition in 4-cyanopyridine crystal. At 77 K, ten distinct phonon modes and an internal mode are observed whereas at 300 K the spectrum shows only six phonon bands and an internal mode. The temperature dependence of spectral pattern and phonon band width suggest that the crystal goes through a phase transition around 120 K. Experimental result suggests that the phase transition is discontinuous with a small structural change.
