摘要：

Employing the techniques that we have described previously for measuring infrared (i.r.) lineshifts, linewidths and line intensities with a tunable diode laser, we have measured these parameters for lines in the R(4) and R(7) multiplets of the v4-fundamental band of 12CH4 at 161, 209 (or 218) and 295 K using He, Ne, Ar, H2, N2, O2, and air as the perturbers. The temperature dependence of the collision-induced lineshift is markedly different from that of the corresponding collision-broadened linewidth. © 1990.
