摘　　要：将低温获取的电子自旋共振波谱与DNA组分及羟基肉桂酸衍生物的前线轨道能量相关联 。Connecting with the character of ESR spectra at 77K and calculated LUMOs,HOMOs the linear relationship between spin transfer efficiency and molar ratios of nucleotide in DNA to sinapic acid or sinapine provides quantitative evidence of long range electron transfer within mixed aggregates.

关 键 词：电子自旋共振 辐射保护机理 芥子酸 长程传递 DNA 芥子酸衍生物
