Abstract

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.
