Abstract
EPR spectroscopy is used to analyse the influence of D2O and NaN3 on the free radicals induced in frozen aqueous solutions of 5'-thymidine monophosphate photosensitized (lambda greater than 320 nm) by proflavine at 205 K. The results can be explained if the production of singlet oxygen during the process is assumed.
摘要
电子顺磁共振光谱法用于分析重水（D2O）和叠氮化钠（NaN3）对在205K下由硫酸原黄素光敏化（波长大于320nm）的5'-单磷酸胸苷冷冻水溶液中诱导产生的自由基的影响。如果假定在此过程中产生单线态氧，那么这些结果就可以得到解释。
