Abstract : Two dye laser systems were purchased for use in energy transfer studies and in unimolecular decomposition experiments. Individual angular momentum states of acetylene in the fourth vibrational state of the CH stretching mode were prepared. It was found that these molecules which contain 10,000 wave numbers of vibrational energy relax at several times the gas kinetic collision rate. There is a striking dependence on the initial rotational state excited implying relaxation of only relatively small amounts of rotational energy. Keywords: Molecular energy transfer, Vibrational energy transfer.
