N2 - To calculate the IR band shapes of CH4 in dense gases and liquids, a model is developed that takes into account both the collisional rotational perturbations and the intramolecular Coriolis coupling. The model is used to analyze the dependence of the V2 and V4 band shapes on the molecular rotational relaxation rate τ-1. The calculations performed make allowance for the Coriolis interaction of the V2, V3, and V4 bands. The strong-collision model is used to treat the rotational relaxation. The simulations reveal a significant distinction in transformations of the V2 and V4 band shapes on increasing τ-1. As τ-1 increases, the V4 band begins to narrow, whereas the "forbidden" V2 band broadens; its shape drastically differs from those typical for the "allowed" vibrational bands with a similar rotational structure.
