摘要：
The optical pumping process in infrared multiphoton induced unimolecular reactions is studied by measuring the pressure dependence of the reaction yield as a function of the laser energy fluence and pulse shape. The dissociation of sulphur hexafluoride is taken as a model reaction. Rate constants for optical pumping near the reaction threshold were found to be directly proportional to the laser intensity for the range of conditions applied. © 1979.
