Photochemistry of dinitrogen pentoxide
Technical Report
·
OSTI ID:6001590
This study examined the gas phase photochemistry and thermal decomposition kinetics of dinitrogen pentoxide, N/sub 2/O/sub 5/. The products of photodecomposition and the quantum yield as a function of pressure have been determined at a wavelength of 254 nm. The rate of thermal decomposition of N/sub 2/O/sub 5/ in the presence of excess NO has been observed between 4 x 10/sup 14/ to 2.8 x 10/sup 19/ molecules cm/sup -3/ and 262 to 307 K. The investigation was conducted by monitoring the infrared absorptions of N/sub 2/O/sub 5/, NO/sub 2/ and HNO/sub 3/. Absorption cross sections for these species were experimentally determined. The techniques used included closed cell decay profiles, with and without photolyzing light, constant illumination of flow systems and modulation of species in a flow system with intermittent photolytic illumination.
