Abstract

We have studied lines mixing induced by collisions in the υ4 IR band of ammonia colliding by hydrogen. We have observed a narrowing effect in the inversion doublets. The lineshapes were analysed using an adapted form of Broquier et al. (4). Comparison between our measurements and a semiclassical calculations shows a good agreement.
