Abstract

Ph radicals were generated by photo-decompn. of nitrosobenzene isolated in solid Ar at 12 K. In this medium the origin of the 1st UV absorption band of nitrosobenzene corresponding to the S0 -> S2 transition was found at 30,260 cm-1. Excitation with an excess energy of ~2200 cm-1 results in very efficient photodissocn. The fragments NO and Ph are stable for many hours. Annealing of the sample >35 ...
