The multiphoton dissocn. of 32SF6 at 10.59 mm was studied as a function of temp. between 223 and 413 K. The obsd. decrease of the reaction yield with increasing temp. varied strongly with the laser energy fluence at the applied conditions. Rate consts. for the unimol. decompn. of SF6 induced by the monochromatic IR radiation were calcd. at 223, 293, and 343 K.
