The DENOX reaction has been investigated by infrared kinetic spectroscopy using excimer laser flash photolysis of NH/sub 3/ at 193nm to produce NH/sub 2/ and color center laser probing of reactants and products. The species NH/sub 2/, OH, H/sub 2/O (in various vibrational states) NO, and NH/sub 3/ could be monitored. All H/sub 2/O signals exhibit a pronounced induction period suggesting that H/sub 2/O is produced in high vibrational states. The time evolution of both low-lying vibrationally excited states and the ground vibrational state is adequately simulated by a model in which stepwise sequential loss of vibrational energy occurs for each step. The spectrum of an electrical discharge in Ar over d-polyacetylene has been investigated using color center laser magnetic rotation spectroscopy.
