The primary quantum yield for formation of OH radicals by photolysis of the monomer and the dimer of formic acid vapor at 222 nm is determined for the first time by a laser photolysis-resonance absorption technique. The measurement is relative to the quantum yield of OH in the photolysis of nitric acid, taken as unity. For the monomer of formic acid, the quantum yield of OH is found to be unity, and for the dimer, essentially zero. The photochemical implications of the results are discussed.
