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

Study: Quantum yield

Authors: G.K. Moortgat, P. Warneck

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

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


Data: (diagram, table, disk): 

Wavelength range: 277 - 355 nm

Resolution: 

Temperature: 298 K

Temperature dependence: 

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.
