Electronic-to-Vibrational Energy Transfer We studied electronic-to-vibrational energy transfer, mostly from spin-orbit excited halogen atoms, for several years. In addition to increasing our understanding of fundamental energy transfer processes, this project led to an understanding of the mechanism of the continuous wave chemical oxygen-iodine laser. The figure above shows the scheme we used to show that I* transfers energy to I2 (25< v < 43). P. L. Houston, "Observation of the Reaction I*(2P1/2) + Br2 IBr + Br*(2P1/2)", Chem. Phys.
