Temperature dependence of the raman shift and raman width of solid parahydrogen: Effect of vibron-phonon scattering

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.
