Comments: Dilute mixtures of hexanal in synthetic air (up to 100 ppm) were photolyzes with fluorescent UV lamps (275-380 nm) in air at 298 K.
The photolysis rates and the absolute quantum yield PHI were found to be slightly dependent on the total pressure. 
At 100 Torr, PHI(100) = 0.43 ± 0.02, whereas at 700 Torr the total quantum yield was PHI(700) = 0.38 ± 0.02.
