Abstract
The relaxation dynamics of vibrationally excited levels of I2(X) are of relevance to the chemical oxygen iodine laser. We have investigated relaxation of I2(v">20) by pulsed laser techniques. Individual ro-vibrational levels were populated by stimulated emission pumping. Collisionally populated levels were monitored via laser excitation of the D-X transition. Preliminary rate constants for vibrational relaxation of I2(v">20) by Ar and H2O are reported. Improved spectroscopic constants for the D state are also presented.
