Abstract

The high-resolution absorption spectrum of the CHD3 molecule has been measured on a Fourier transform spectrometer in the region of the nu5 and nu3/nu6 bands and analyzed for the first time by taking into account a1 - a2 (K = 3) splittings of the ground vibrational state. The problem of ambiguity in determining the corresponding epsilon; parameter of the ground vibrational state was solved on the basis of the analysis of the rotational structure of the nu5 band. Numerous a1-a2 splittings for the states with Kupper = 1, 2, 4, 5, 7 in the nu5 and nu6 bands are described. Copyright 1997 Academic Press. Copyright 1997Academic Press
