Substance: formaldehyde					Other Names: methanal; methylene oxide

Formula: CH2O						CAS-No.: 50-00-0

Study: photolysis, quantum yield


Authors: G.K. Moortgat, P. Warneck

Title: CO and H2 quantum yields in the photodecomposition of formaldehyde in air

Journal/Source: J. Chem. Phys., 70, 3639-3651, (1979)


Data:

Energy/Wavelength range: 277 - 355 nm

Resolution: 

Temperature: 298 K

Temperature dependence:  no

Pressure/Concentration: 380 - 800 Torr

Phase: gas

pH:
 

Comments: In the 290–330 nm wavelength range the quantum yields showed no pressure dependence between 380 
and 800 Torr of air, at 355 nm the quantum yields increase with decreasing pressure.
