Generally these radicals may be divided into two groups. Primary radicals that are formed through photolysis or thermolysis of abundant precursors or through direct transfer from the gas phase may be distinguished from secondary radicals which are formed through bimolecular radical switching reactions of reactive precursors. The dichloride radical anion (Cb") belongs to the latter group. It is thought to play a role in
