Popis: The infrared bands ν 2 and ν 5 of CH 3 Br have been measured at a resolution of 0.015 cm −1 . The lines due to the isotopic species CH 3 79 Br and CH 3 81 Br were resolved and altogether about 3000 lines were assigned. The bands were analyzed simultaneously by taking into account the xy -Coriolis resonance between the states v 2 = 1 and v 5 = 1. A local perturbation observed in ν 5 could be explained in terms of a (1,−2) resonance between v 2 = 1 and v 5 = 1. Some perturbation allowed transitions could be assigned and they give an equation between A 0 and D 0 K .
