Results of infrared laser induced fluorescence studies on cyclopropane are presented. Molecules were excited from the ground state to the v10 level of cyclopropane using a Q-switched CO2 laser operating on either the P(14) or P(20) transition of the 9.6 μ branch. Fluorescence was observed from the v6, v8, v10 + v11 and v5 + v10 levels of cyclopropane. The self-deactivation of vibrationally excited cyclopropane through V → T/R processes was found to have a rate of 8.0 ± 1.5 ms-1 torr-1. Deactivation by rare gas collisions was also studied with comparison to simple V → T and V → R theories. V → V equilibration processes are discussed involving the v6, v8, v10, v11, and v10 + v11 levels.
