Abstract

A careful rotational analysis of the ground vibrational state of the CHD3 molecule is made on the basis of the ground state combination differences method using, as the initial information, transitions from 12 infrared absorption bands: ν3(A1), ν6(E), ν5(E), 2ν3(A1), 2ν6(A1), 2ν6(E), ν3 + ν6(E), 2ν5(A1), 2ν5(E), ν3 + ν5(E), ν5 + ν6(A1 + A2), and ν5 + ν6(E). More than 2500 "forbidden" transitions were used to determine the parameters C, DK, and HK. a1 - a2 (K = 3) splittings in the ground vibrational state were found and analyzed.
