Figure 1. Density normalized absorption coefficients α(ω)/ν1ν2 of He + CH4. Dots: Experimental data at 353°K by Afanas’ev et al. (7). Solid line: Calculated spectra determined by fitting the range and amplitude of only the isotropic (A = 0) overlap contribution to the dipole induction. For all the temperatures above 150°K the displayed spectra are shitkl up by one decade; the maximum of the absorption coefficient at each temperature is near 10-6 cm-1/amagat2.
