摘要：

Quantum yields for the products CH3CHO, CO2 and CH3COOH in the 350 nm photodecomposition of pyruvic acid are 0.48 +/- 0.01, 1.27 +/- 0.18 and 0.14, respectively, as measured in air at atmospheric pressure. In the presence of NO2 the quantum yield for CH3CHO was reduced to 0.30 +/- 0.04 and peroxyacetyl nitrate was formed with a quantum yield of 0.15 +/- 0.02. This is taken to indicate the formation of acetyl radicals in one of the primary processes.
