title: Infrared Optothermal Spectroscopy of N(2)- and OC-DCCH: The C-H Stretching Region.
abstract: High-resolution optothermal laser spectroscopy is reported for the C-H stretching vibrations of the binary complexes formed between monodeuterated acetylene and carbon monoxide and nitrogen. In contrast with a previous study of the corresponding C(2)H(2) complexes, where the C-H fundamental spectra were highly perturbed [R. D. Beck, A. G. Maki, S.-H. Tseng, and R. O. Watts, J. Mol. Spectrosc. 158, 306-317 (1993)], the present spectra are well described by a simple linear-rotor Hamiltonian. This is presumed to result from the fact that the C-H vibration in the monodeuterated complexes is decoupled from the intermolecular degrees of freedom. Copyright 2000 Academic Press.
