Abstract
Quantum calculations are reported for the high-resolution spectra and dynamics of the first and second overtone of the acetylenic C-H stretch (ν_1) in propyne. The calculational method used is similar to that we have used earlier for lower energy states. Lack of low-order Fenni resonances lead to a vibrational superexchange mechanism of decay of the initially populated bright state. The importance of the total density of states and quartic couplings between zeroth-order states is investigated. Comparison with recent experimental results is discussed.
