Gas-phase absorption cross sections of 2-nitrobenzaldehyde and benzaldehyde in the 285-400Â nm region, and photolysis of 2-nitrobenzaldehyde vapor at 308 and 351Â nm

Gas-phase UV absorption cross sections of 2-nitrobenzaldehyde and benzaldehyde. Low vapor pressure compound cross section determination by cavity ring-down spectroscopy. Photolysis of 2-nitrobenzaldehyde vapor at 308 and 351 nm. Photolysis rate constants and lifetimes of 2-nitrobenzaldehyde. Gas-phase photolysis is a major process for removing 2-nitrobenzaldehyde from the atmosphere.
