HN/sub 3/, CH/sub 3/NH/sub 2/, and N/sub 2/H/sub 4/ were photolyzed with an ArF (193 nm) excimer laser. Emissions from excited NH in the (A/sup 3/..pi..) and the (c/sup 1/..pi..) states and also from CN(B) and CH(A,B,C) were observed in the wavelength range 200-500 nm. The NH fluorescence was investigated in detail and in comparison with the recently observed formation of NH(A/sup 3/..pi..) from ammonia. The formation processes and the rotational population of the imidogen radicals, their lifetimes, and their quenching by the parent molecules were studied.
