Abstract首次用脉冲辐解时间分辨方法研究了etoposide(VP16)在水溶液中与N_3(SCN)_2~-和e_(aq)~-之间发生的单电子氧化还原反应.测定了 VP16的阴离子自由基、脱质子中性自由基的特征吸收谱;测得VP16与e_(aq)~-;N_3;(SCN)_2~-的绝对反应速率常数分别为2.7×10~9;3.2×10~9和2.5×10~8dm~3·mol~(-1)·s~(-1).研究表明;水溶液中的VP16可为248nm激光光电离;光电离的瞬态产物为阳离子自由基及脱质子中性自由基;并且测定了其酸碱电离的pK值.测得SO_4~-自由基单电子氧化VP16的反应速率常数为2.8 ×10~9dm~3·mol~(-1)·S~(-1).
