The modeling of the collision-induced rototranslational absorption spectra for H2-CH4 molecules is described. The intermolecular potentials of the molecular complex are analyzed. The absorption coefficient is dependent on the molecular structure and the line-shape formulas for induction by hydrogen and methane are provided. Dipoles induced by an electric multipole field are examined. The measurements of the collision-induced absorption spectrum of the H2-CH4 system at 195 and 297 K are fitted to the Sutter et al. data. The relation between spectral components and H2-CH4 intermolecular potential are studied using the Hanley-Klein potential model (1972). Absorption coefficients of H2-CH4 are presented. 51 references.
