The radical or reactive intermediates discussed in Chapter 2 are included in the term photochemical oxidants for the purpose of this chapter. Of the reactive intermediates discussed, only the hydroperoxy, HO2, and singlet oxygen, O2 (a A), radicals have a lifetime long enough... [Pg.280]

The change of p with solvents may be due to either a change of the lifetime of singlet oxygen (1 /kB) or a change of the reactivity of the substrate toward singlet oxygen (kg), or both. Systematic studies of solvent effects are, therefore, very much needed. [Pg.22]
