High resolution infrared spectrum of methyleneimine, CH2NH,in the 3 mgr;m region

摘要

The infrared spectrum of the shorthyphen;lived methyleneimine, CH2NH, was obtained in the gas phase with a resolution of about 0.01 cmminus;1from 2800 to 3200 cmminus;1, using the Kitt Peak National Observatory Solar Fourier Transform Spectrometer. The ngr;2band and the high order Coriolis coupled ngr;3and 2ngr;5bands have been analyzed rotationally. Several hundred transitions have been fitted and accurate band origins and rotational constants have been determined for each of the bands.
