| Abstract: | Absorption and fluorescence techniques were used to study special features of the XeCl laser-induced phototransformation of phenols in water and to compare the results obtained with those of photolysis of phenol solutions exposed to the UV radiation from mercury lamps. XeCl laser-induced phenol photolysis provided photoproducts not found on exposure to UV radiation. This is related to the two-photon population of highly excited phenol states under high-power laser pumping, which gives rise to a new phototransformation reaction pathway. |
