4. The phosphorescence decay (Ip) of benzoic acid in a solid matrix of isopentane-diethyl ether, at 77K, is shown in the table. Calculate the lifetime of the triplet state. Ip (arbitrary units) 55.0 46.7 39.7 33.6 28.5 20.7 14.9 10.7 Time / s 0.0 0.5 1.0 1.5 2.0 3.0 4.0 5.0 Clue: i) consider the intensity of phosphorescence as directly proportional to the concentration of the triplet state, ii) the decay of the triplet state follows first order kinetics.
