Studies of Energy Transfer Processes of Relevance to Chemically and Optically Pumped Lasers.
Abstract
The relaxation dynamics of vibrationally excited levels of 12(X) are of relevance to the chemical oxygen iodine laser (COIL). Rotational and vibrational energy transfer rate constants have been measured for selected levels with v">20. The collision partners He, Ar, I2,Cl2, 02, and H20 were investigated. A numerical model that relates state-to-state energy transfer rate constants to I2+ deactivation processes in COIL has been developed. The results for H2O show that the true deactivation rate constant is about an order of magnitude smaller than the estimate used in current computer simulations of COIL systems. Energy transfer from 02(a1A) and I(2P1/2) to 12(X) has been investigated. The nascent vibrational distribution resulting from I(2Pl/2)+I2(X) collisions was characterized, and improved spectroscopic constants for the D state of I2 are reported. Jet-cooling and emission spectroscopy techniques have been used to characterize the D'(2)-A'(2) and Beta(l)-A(l) ion-pair to valence state transitions of iodine monobromide.
