Abstract

The high-resolution Fourier transform spectra of the CHD3 molecule have been recorded and assigned between 1850 and 2450 cm-1. To verify the assignments and to span a more complete energy manifold in the excited vibrational states, the hot bands 2v3 - v3, v3 + v6 - v3, v3 + v6 - v6, and 2v6 - v6 near 1000 cm-1 were used. The assignment presented in this study is based on the recent ground state rotational energies determined by Ulenikov et al. (J. Mol. Spectrosc. 186 (1997) 230). As a result the vibrational-rotational energies in the (v3 = 2,A1), (v3 = v6 = 1,E), (v6 = 2,A1), (v6 = 2,E), (v4 = 1,E), (v2 = 1,A1), and (v3 = v5 = 1,E) states have been refined and extended.
