在296 K下，测量了过氧化氢蒸气和中性过氧化氢水溶液在195 ~ 350 nm波长范围内的吸收截面。分光光度法的程序进行了描述，并报告的横截面与其他研究人员获得的值进行了比较。计算了大气H_2O_2直接吸收未散射太阳辐射时的光解系数，并给出了不同太阳天顶角下这些系数的垂直分布。
Absorption cross-sections of hydrogen peroxide vapor and of neutral aqueous solutions of hydrogen peroxide were measured in the wavelength range from 195 to 350 nm at 296 K. The spectrophotometric procedure is described, and the reported cross-sections are compared with values obtained by other researchers. Photodissociation coefficients of atmospheric H2O2 were calculated for direct absorption of unscattered solar radiation, and the vertical distributions of these coefficients are shown for various solar zenith angles.
