K Fine Structure in the 2ν1 Band of CHD3

Abstract
The K structure in the P and R branches of the 2ν1 band of CHD3 has been resolved permitting the determination of the following molecular constants: ν0=5865.02, B″=3.2777, B′=3.2396, A′—A″=−0.0181, DJ=3.9×10−5, and DJK=−4×10−5 cm−1. The Q branch is synthesized from these data and compared with the spectrometer trace of that branch.
