## Abstract The Raman band of the Cο£ΎOβstretching vibration of methyl ethyl ketone has been recorded in the temperature range 233 K to 343 K, and also at 293 K in various solvents at various concentrations. This polarized Raman band shows asymmetry and a nonβcoincidence of the isoβ and anisotropic f
We discuss the relationship between vibrational population relaxation, loss of phase coharence, and the homogeneously broadened spontaneous poklzed Raman linewidth. We derive a general equation reltmg these quantitres. and show that extension of the simple model (where the coupling to the heat bath
