摘要：

Using experimentally observed solar irradiances and extinction coefficients, the first-order rate constant for the photolysis of ozone to form singlet oxygen is calculated. The minimum concentrations of O2(1Δg) in polluted urban atmospheres are then estimated on the basis of available quenching data. It is shown that these concentrations are sufficient to make O2(1Δg) a much more important oxidizing agent than atomic oxygen in polluted environments. © 1969, American Chemical Society.
