The rate of reaction of oxygen atoms with nitric oxide has been studied at several pressures (0.62, 0.85, 1.11 mm Hg) by measuring the relative intensities of the oxygen afterglow. The consumption of O atoms was observed as a three-body recombination (NO+O+M→NO2+M). At room temperature the reaction coefficient was found to be k2=7.6×10-32 cm6 molecules-2 sec-1, with an average deviation of 6.5%. The third body was mainly argon.
