Perturbations in the infrared spectrum of monofluoroacetylene, and their relationship to intramolecular vibrational energy redistribution

Holland, J. K., Lawrance, W. D. and Mills, I. (1992) Perturbations in the infrared spectrum of monofluoroacetylene, and their relationship to intramolecular vibrational energy redistribution. Journal of Molecular Spectroscopy, 151 (2). pp. 369-377. ISSN 0022-2852 doi: 10.1016/0022-2852(92)90572-6

Abstract/Summary

Several high-order vibration-rotation perturbations in the high-resolution infrared spectrum of monofluoroacetylene, HCCF, are assigned and analyzed in detail. They result in avoided crossings in the rotational structure of several bands, and precise values for the effective high-order terms in the Hamiltonian have been determined. The significance of these results for intramolecular vibrational redistribution is discussed.
