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 CHD molecule have been recorded and assigned between 1850 and 2450 cm(-1). To verify the assignme nts and to span a more complete energy manifold in the excited vibrational states, the hot bands 2 nu(3) - nu(3), nu(3) + nu(6) - nu(3), nu(3) + nu(6) - nu(6), and 2 nu(6) - nu(6) near 1000 cm(-1) were used. The assignment pr esented in this study is based on the recent ground state rotational energi es determined by Ulenikov et al. (J. Mol. Spectrosc. 186 (1997) 230). As a result the vibrational-rotational energies in the (nu(3) = 2,A(1)), (nu(3) = nu(6) = 1,E), (nu(6) = 2,A(1)), (nu(6) = 2,E), (nu(4) = 1,E), (nu(2) = 1, A(1)), and (nu(3) = nu(5) = 1,E) states have been refined and extended.
