Time-resolved infrared-ultraviolet double resonance spectroscopy is used to measure collision-induced rovibrational energy transfer in the v 2+3v3 region (∼11 600 cm-1) of gas-phase acetylene. Of particular interest is rotationally resolved V-V transfer between the Fermi-coupled 2133 and 112 34351 levels, for which the rate is relatively high (approximately 13% of the Lennard-Jones collision rate) and the relevant rovibrational states markedly perturbed.
