Corrections du 2e et du 3e ordre à l'énergie de vibration-rotation des molécules polyatomiques dans le cas d'une résonance de coriolis

Abstract

2014 When resonance between vibrational frequencies of polyatomic molecules occurs, the contact-transformation method proposed by Shaffer, Nielsen and Thomas is not directly applicable. It has been shown by Nielsen, then by Grenier-Besson, Amat and Nielsen, that in this case the transformation function should be a modified one. This problem is treated here in the case of the Coriolis resonance, when the question of the computation of the rotationvibration énergies is extended to a third order of approximation.
