When a mixture of H/sub 2/ and Cl/sub 2/ is irradiated with 488-nm radiation, the evolution of heat in the gas is governed by the rate of chain reaction. The optoacoustic effect, produced by modulating the amplitude of the radiation and recording the resulting acoustic signal, thus acts as a monitor of the chemical reaction rate in a manner analogous to the technique of intermittent activation. NO is shown to act as a potent inhibitor of the H/sub 2/-Cl/sub 2/ reaction by rapid reaction with Cl radicals. 21 references, 2 figures, 1 table.
