Evidence of rotational and vibrational relaxation in the isotropic Raman spectra of CO and N2
Golubev N. S. , Orlova N. D. , Platonova L. A.
The theoretically predicted relationship between the width of the isotropic Raman-scattering band and the angular-momentum correlation time has been tested experimentally for the first time. The correlation time was measured by an NMR method. Experiments were carried out on CO and N2 in various gas mixtures. A vibrational broadening is exhibited by CO in C02; the mechanism for this broadening is not clear.
