Comments: The relative quantum yield for the production of radical products, H + HCO, from the UV photolysis of formaldehyde 
(HCHO) has been measured using a pulsed laser photolysis-pulsed laser induced fluorescence (PLP–PLIF) technique across 
the 30400-32890 cm-1 (304-329 nm) spectral region.
Yields were normalized to a value of 0.69 at 31750 cm-1 based on the current recommendation of Sander et al. (JPL Report 17, 2011).
