Abstract: | The ν1 band profile of isotropic Raman spectrum of pure CD4 and its mixtures with Ar and Kr is recorded in the temperature range 140–360 K at pressure of pure CD4 ranging from 4 to 20 atm and at total pressure of gas mixtures in the interval 4–160 atm. The dependences of the band shape on temperature and density are analyzed. The coefficients of the CD4 band broadening by Ar and Kr are determined, and the decisive role of vibrational contributions, in particular of the intramolecular energy transfer, is pointed out. |
