Reflection-absorption infrared (RAIR) spectroscopy has been used to explore the low temperature condensed-phase photochemistry of atmospherically relevant organic nitrates for the first time. Three alkyl nitrates, methyl, isopropyl, and isobutyl nitrate together with a peroxyacyl nitrate, peroxyacetyl nitrate (PAN), were examined. For the alkyl nitrates, similar photolysis products were observed whether they were deposited neat to the gold substrate or codeposited with water. In addition to… Expand

Absorption spectra and aqueous photochemistry of β-hydroxyalkyl nitrates of atmospheric interest
Molar absorption coefficients were measured for select alkyl nitrates and β-hydroxyalkyl nitrates in methanol. The presence of the β-hydroxyl group has a relatively minor effect on the absorptionExpand


Cold-surface photochemistry of primary and tertiary alkyl nitrites.
The results point to cold surface processing of alkyl nitrites as a potential environmental source of nitrous oxide and the reaction rates for cis and trans conformer decay were found to be significantly different. Expand
Photodecomposition of Methyl Nitrite Trapped in Solid Argon
Abstract : The threshold wavelength for the photolysis of methyl nitrite isolated in solid argon at 14 deg K has been determined to be near 370 nm. Photolyzed samples show prominent infraredExpand
Photolysis of Nitromethane and of Methyl Nitrite in an Argon Matrix; Infrared Detection of Nitroxyl, HNO
The photolysis of nitromethane in solid argon at 20°K gives methyl nitrite. All other products can be explained in terms of the secondary photolysis of methyl nitrite. This work provides a definitiveExpand
Fourier transform infrared spectroscopic study of the thermal stability of peroxyacetyl nitrate
The unimolecular decomposition of peroxyacetyl nitrate (PAN) to form methyl nitrate and carbon dioxide has been studied over the temperature range 298-338 K by Fourier transform infrared spectroscopyExpand
Atmospheric fate of several alkyl nitrates Part2UV absorption cross-sectionsand photodissociation quantum yields
The UV absorption cross-sections of methyl, ethyl and isopropyl nitrate between 233 and 340 nm have been measured using a diode array spectrometer in the temperature range 240–360 K. TheExpand
Wavelength dependence of nitrate radical quantum yield from peroxyacetyl nitrate photolysis: experimental and theoretical studies.
In both molecules, photodissociation of both O-O and O-N bonds occurs via excitation to predissociative electronic excited states and subsequent redistribution of that energy as opposed to directly dissociative excitations. Expand
Investigation of the loss processes for peroxyacetyl nitrate in the atmosphere: UV photolysis and reaction with OH
The UV absorption cross sections of peroxyacetyl nitrate (PAN), CH 3 C(O)O 2 NO 2 , have been measured as a function of temperature (298, 273, and 250 K) between 195 and 345 nm using a diode arrayExpand
Direct measurements of the photolysis rate coefficients and Henry's law constants of several alkyl nitrates
We report the direct measurement of the photolysis rate coefficients of ethyl, n-propyl, n-butyl, and 2-butyl nitrate to NO2 and the alkoxy radical, RONO2 + hν → RO + NO2, using a luminolExpand
The Quantum Yield of NO3 from Peroxyacetyl Nitrate Photolysis
Peroxyacetyl nitrate (PAN) vapor was photolyzed at 248 nm and the NO3 photoproduct was detected by laser-induced fluorescence. The quantum yield for the production of NO3 was determined by comparisonExpand
