High-resolution Fourier transform spectrum of the CHD₃ molecule in the region of 1850-2450 cm^-1: Assignment and preliminary analysis

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.
