Comments: The infrared and ultraviolet-visible absorption cross sections, effective quantum yield of photolysis, 
and OH, Cl, and NO3 reaction rate coefficients of CHF2CHO are reported.
An effective quantum yield of photolysis of CHF2CHO equal to 0.30 ± 0.05 over the wavelength range 290-500 nm has been determined.
