Abstract
E.S.R. spectra of different DNA-quinacrine complexes show as well at 77 K as at 293 K that there exists an electron transfer from the bases to quinacrine facilitated by the overlap of the theta-orbitals of the bases and the intercalated dye. The transfer range may extend over more than 25 or 50 nucleotides depending on the intercalation model considered.
摘要
不同DNA-喹吖因复合物的电子自旋共振（E.S.R.）光谱显示，在77K和293K时，由于碱基的θ轨道与插入染料的重叠，存在从碱基到喹吖因的电子转移。根据所考虑的插入模型，转移范围可能延伸超过25个或50个核苷酸。
