Abstract
Infrared and Raman vibrational bands of the esters of crotanic acid and picolines are used to compute the respective correlation functions. Both short time and long time behaviour of the correlation functions are examined and compared with the correlation functions of the freely rotating molecule. For the picolines, three distinct bands are observed in the region $15-120 cm^{-1}$ and three relatively strong bands in the region $120-450 cm^{-1}$. The various contributions to the band shape are discussed in the light of the earlier NMR and dielectric data and the present IR and Raman $data.^{1-3}$
