| Abstract: | Mixtures of N2O, CO, and NO in excess H2 were photolyzed at 213.9 nm and 298°K. The initially formed O(1D) atoms from the photolysis of N2O abstract an H atom from H2 permitting a study of the competition:  From the CO2 yield the relative rate coefficient k1/k2 is obtained. It is found to be slightly dependent on pressure for total pressures (mainly H2) of 95.5 to 768 torr. However, the values are near the high-pressure limiting value which is found by extrapolation to give k1∞ = 1.2 × 10?11 cm3/sec based on k2∞ = 3.55 × 10?13 cm3/sec. |
