Abstract

The infrared bands line-mixing effects of methane perturbed by nitrogen were discussed at different pressures. The spectral shapes of the ν₂, ν₄ and ν₃ bands were compared at room temperature while the ν₃ region was employed for the investigation of thermal effects. The effects of collisions in the ν₄ region's spectra were calculated at the room temperature. The Coriolis coupling between ν₂ and ν₄ vibrational states resulted in the failure of evolution modeling with increasing pressure of absorption.
