✦ Synopsis

The dependence of photoinduced radical anion formation upon exciting light intensity has been studied for glassy solutions of tetracyanobenzene (TCNB) in ether-isopentane and 2-methyl-tetrahydrofuuran (MTHF) nt 77 Ii. It has been found thatinetller-isopentnnc _Jnss theTCNB anion is formed biphotonically via the lowest excited triplet state of the 1:l TCNB-ether CT complex, whereas in MTHF glass the ionic pho:odissociation of the TCNB-XITHF CT complex OCCUIS monophotonially in its lowest excited singlet state.
