摘要：

We show that, in the Raman spectrum of very low-density gases, the.. branch of the nu(1) band of methane and deuteromethane has asymmetric contour. With increase in the gas density, the band contour becomes more symmetric and broadens. The band shape is described by the Voigt curve. Possible mechanisms of the vibrational broadening of v(1) - dephasing and intermode exchange of vibrational energy - are analyzed. Both mechanisms may be efficient in the band broadening.
