摘要

研究受,60,Co ,γ,射线照射的知母宁、小牛胸腺DNA和它们的分子混合物（知母宁和DNA中的核苷酸摩尔比为1:1）的ESR波谱，从波谱特征（g因子、峰宽、峰高等）变化，说明辐照DNA的电子自旋向知母宁分子转移，计算出自旋转移比率（TR值）为5.63,推断知母宁通过电子自旋转移修复DNA分子使DNA的自由基消失。

Abstract

ABCTRACT The electron spin resonance (E. S. R) spectra of γ-irradiated DNA, chinonin and their mixture (the nucleotide and chinonin in mol ratio of 1:1) were investigated at normal temparature. Based on g value, the shape and width and signal amplitude of ESR spectra, We may concluded that the electron spin may transfer from DNA to chinonin with a transfer ratio of 5.63.
