Electronically excited NO was produced by irradiation with the 2144 and 2265 A lines of the cadmium arc at nitric oxide pressures from 20 to 600 mm. The products were nitrogen and nitrogen dioxide. A pressure drop accompanied the reaction equivalent to the nitrogen produced. The mechanism is given. The quantum yield of nitrogen formation was independent of irradiation time and incident intensity. Its falloff with pressure was less than a factor of two, even at 20 mm. These results, when combined with the radiative lifetime measurements of Callear and Smith, show that removal of NO occurs on nearly every collision. Author
