Abstract:
We present a model for vibron-phonon scattering in molecular crystals. A general kinetic equation
for the vibrons is derived. We use this equation to calculate the frequency shift and dephasing rate of the
vibrons as functions of temperature. We find good agreement between the calculated results and the
experimental observations for the Raman shift and Raman width of the fundamental vibrational Raman
transition of solid parahydrogen.
