 Title: THE RESOLVED ROTATIONAL ENERGY TRANSFER IN $^{13}CH_{3}F$ Creators: McCormick, Rodney I.; Skatrud, David D.; De Lucia, Frank C. Issue Date: 1986 Publisher: Ohio State University Abstract: Collisional energy transfer in optically pumped $^{13}CH_{3}F$ has been studied in a time resolved infrared/millimeter wave multiple resonance experiment. In this experiment a Q-switched $CO_{2}$ laser is used to rapidly populate $J=5$ in the $v_{3}=1$ excited vibrational state. The time evolution of the relaxation of the non-equilibrium population is then monitored via the millimeter wave probe. By appropriate selection of the rotational transition to be monitored. J changing, K changing, and v changing collisions can be studied with a minimum of theoretical deconvolution. A model has been developed to predict state-to-state population transfer rates. This model and the experimental results will be compared.
