Data: table

Energy/Wavelength range: 275 - 380 nm

Resolution: 

Temperature: 298 K

Temperature dependence: no

Pressure/Concentration: 100 - 700 Torr (total pressure)

Phase: vapor (dilute mixtures of n-heptanal in synthetic air (up to 100 ppm))

Comments: The photolysis rates and the absolute quantum yields Phi were found to be slightly dependent on the total pressure. At 100 Torr, Phi(100) = 0.36 ± 0.03, 
whereas at 700 Torr the total quantum yield was Phi(700) = 0.31 ± 0.01.
