摘要

用脉冲辐解动态吸收光谱法研究了Br,2,•-,、Cl,2,•-,自由基引发N-二异丙基磷酰化甲硫氨酸（NDM）与色氨酸（TrpH）的分子间电子转移机理，测定电子转移反应的速率常数，从分子结构观点解释了磷酰基对电子转移机理的影响。

Abstract

In this paper, the intermolecular electrontransfer (ET) involving N-phosphoryl methione (NDM) and tryptophan (TrpH) initiated by Br,2,·-, and Cl,2,·-, anion radicals in aqueous solutions have been studied using pulse radiolysis and kinetic spectrophotometric monitoring techniques, a series of rate constants of ET have been determined and the influence of N-phosphoryl group on the mechanism of ET has been explained structurally.
