芥子酸及其衍生物辐射保护DNA的电子自旋共振研究

摘要

Connecting with the character of ESR spectra at 77K andcalculated LUMOs, HOMOs the linear relationship between spin transfer efficiencyand molar ratios of nucleotide in DNA to sinapic acid or sinapine provides quantitativeevidence of long range electron transfer within mixed aggregates.%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,依据自旋自DNA向芥子酸及其衍生物的转移效率与核苷酸和后者摩尔比的线性关系揭示混合堆集物中电荷长程传递的证据.
