Comments: Absolute quantum yields have been measured for the gas phase photolysis of H2CO and D2CO as a function 
of excitation energy.
For H2CO the total photochemical quantum yield was PHI(total) =1.0 ± 0.1 for lambda < 326 nm and 0.68 at lambda = 353 nm. 
For D2CO, PHI(total) = 1.0 ± 0.1 for lambda < 331 nm and drops to zero near the band origin.
