✦ Synopsis

The high-resolution absorption spectra of several infrared bands of NH 2 Cl molecule have been observed and analyzed. Rotational lines of amino wagging and scissoring fundamental bands are split by about 0.2 cm Ϫ1 through the amino inversion motion. The shape of the inversion potential and the barrier height are considered by comparing the results of the experimental observations and an ab initio MO calculation. The amino twisting band of amine molecule has been observed for the first time in the gas phase. The intensity of the transition seems to be induced through a Coriolis interaction with the intense amino wagging band.
