Study of melting transition on biphenyl by Raman scattering
Source abstract
Abstract
Vibrational properties of the biphenyl at around the melting transition temperature are investigated by Raman scattering. Nearly all the vibrational modes exhibit anomalous changes on the frequency, width, and intensity at around the melting temperature. The librational modes disappear at above the melting temperature. The energy separations between the 1220 and 1280 cm−1 modes and between the modes at around 1600 cm−1, as well as the intensity ratio of the last two modes, all show anomalous changes at around the melting transition temperature.
