Abstract
The infrared spectrum of CH3Br has been analyzed between 1 200 and 1 500 cm-1 taking into account the x - y Coriolis resonance between the two fundamental levels υ2 = 1 and υ 5 = 1. The band centers were found respectively at 1 305.907 and 1 442.885 cm-1 and the ζx2,5 coupling term was determined to be 0.617.
Résumé
Le spectre infrarouge de CH3Br a été analysé entre 1 200 et 1 500 cm-1 en tenant compte de la résonance de Coriolis en x- y entre les deux niveaux fondamentaux v2 = 1 et υ5 = 1. Les centres de bande ont été trouvés respectivement à 1 305,907 et 1 442,885 cm-1 et le terme de couplage ζx2,5 vaut 0,617.
