Diode laser spectroscopy of the ν6 band of 13CH 3l and the ν″ 6 band of 12CH 2Dl
Abstract
The ν6 band of 13CH 3I and the ν″ 6 band of 12CH 2DI have been recorded under Doppler-limited resolution in the region 820-866 cm -1 using a tunable diode laser spectrometer. For 13CH 3I the constants for the ν6 band were determined by simultaneous analysis of seven pQ( J, K) branches and several pP( J, K) and pR( J, K) transitions. For 12CH 2DI, the slight asymmetry introduced by the single D atom gives rise to noticeable asymmetry effects in the spectra of some of the pQ( J, K) subbands. From the analysis of six such subbands, the molecular constants for the ν″ 6 level were determined.
