Abstract

Investigation of relaxation processes by means of high resolution Raman spectroscopy (HRRS) or coherent antistokes Raman spectroscopy (CARS) has been developed in recent years for testing and modelling potentials of molecular crystals1,2 like N2 3, CO2 4, naphtalene5, anthracene6, benzene7 or CS2 8. Until now the linewidth (or equivalently the lifetime) of the optical internal and external phonons were measured at different temperatures and at constant (ambient) pressure. Even though relaxation theory assumes constant volume for all temperatures, experimental and calculated data are in good agreement as has been demonstrated on CO2 4 or naphtalene5.
