本文用STM/ STS（scanningtunnelingmicroscopy/scanningtunnelingspectroscopy）技术测量了两种类型（仅A-T对和仅G-C对）双链DNA分子碱基处的局域电子态密度谱。讨论了A-T对和G-C对电子结构的差异与电荷转移机制的关系。
Local electron density of state spectra at the bases sites in the two types (A-T pairs only and G-C pairs only) of doublestranded DNA molecules is measured with the use of STM/ STS (scanning tunneling microscopy/scanning tunneling spectroscopy) technique. The difference of electronic structure between A-T pairs and G-C pairs is discussed in relation to the charge-transfer mechanisms in these molecules.
