REACTIONS OF OH RADICALS WITH INORGANIC-COMPOUNDS IN THE GAS-PHASE

In the present article we discuss the reactions of hydroxyl radicals with inorganic compounds in the gas phase, which include some important atmospheric reactions, and which have been the subject of a large number of experimental and a few theoretical investigations in recent years. The discussion focuses on rates and mechanisms, but it is not intended as an exhaustive evaluation of kinetic parametes in the literature. In particular, for the reactions for which kinetic data are well established, the recommended kinetic parameters provided by recent evaluations are given, along with results published since the evaluations. Greater attention is given those reactions for which the kinetic or mechanistic data are uncertain or controversial, or which are not included in the recent evaluations. The aim is to draw attention to those areas requiring further experimental or theoretical study. The discussion will deal mainly with kinetic data obtained by the discharge flow and flash photolysis techniques.
