Ozone was photolyzed at room temperature in the presence of N 2 O at 2537 Å and 2288 Å to produce O( 1 D ) atoms. These atoms can react with either O 3 or N 2 O viaFrom the quantum yield of N 2 , the relative rate constants k 6a / k 6 and k 2 / k 6 could be obtained, where k 6 + k 6a + k 6b . The former rate constant ratio was found to be 0.37 ± 0.03 at 2537 Å and 0.33 ± 0.03 at 2288 Å, in good agreement with an earlier report from our laboratory. The ratio k 2 / k 6 was found to be 2.6 at 2537 Å, but 4.1 at 2288 Å. The difference in the two numbers, if real, may reflect differences in reactivity due to different amounts of excess translational energy in the O( 1 D ) atom at the two wavelengths.
