Title: 2-Nitrobenzaldehyde as a Chemical Actinometer for Solution and Ice Photochemistry 

Journal/Source: J. Photochem. Photobiol. A: Chem., 209, 186-192, (2010); doi:10.1016/j.jphotochem.2009.11.013 


Data: table, diagram

Energy/Wavelength range: 240 - 430 nm

Resolution: 

Temperature: 274 - 298 K

Temperature dependence: yes

Pressure/Concentration: 

Phase: solution (water and/or acetonitrile) and in/on water ice

Comments: The authors have measured the light absorbance and photochemical properties of 2-nitrobenzaldehyde in 
solution (water and/or acetonitrile) and in/on water ice.
A quantum yield of 0.41 for 2NB photolysis for both solution and water ice is recommended. The quantum yield is independent of wavelength.
