Abstract
The measurement of the relative quantum yield of singlet oxygen formation, a simple process without tedious sample deoxygenation, is shown to furnish data on the interaction of the excited photosensitizer with any additive (in this case stable free radicals) given to the sample. The rate constants derived from such measurements are in good agreement with direct determination of the corresponding values.
摘要
单线态氧生成相对量子产率的测量是一个无需繁琐样品脱氧的简单过程，结果表明，该测量能提供有关激发态光敏剂与样品中添加的任何添加剂（在此情况下为稳定自由基）相互作用的数据。通过此类测量得出的速率常数与相应值的直接测定结果高度吻合。
