Competition between collisions and optical pumping in unimolecular reactions induced by monochromatic infrared radiation

The optical pumping process in IR multiphoton induced unimol. reactions was studied by measuring the pressure dependence of the reaction yield as a function of the laser energy fluence and pulse shape. The dissocn. of SF6 is taken as a model reaction. Rate consts. for optical pumping near the reaction threshold were directly proportional to the laser intensity for the range of conditions applied.
