Abstract:

The photoionization of N3- in aqueous solutions was investigated by methods of steady photochemistry and flash photolysis. Evidence is presented for the occurrence of photoionization from the charge-transfer-to-solvent CTTS excited state of N3-. The azide radical which results from this process was identified spectroscopically and some of its properties were investigated. Only about 15 of the CTTS excited ions undergo photoionization and the rest produce NH2OH, possibly by first being internally converted to the n, pi state. Ammonia is produced from the reduction of hydroxylamine by solvated electrons. This is indicated by the effect of electron scavengers on the photolysis of N3- at 2144A. The study of the photochemistry of NCS- has been completed and its relation to the photochemistry of N3- is discussed. Author
