CNDO/2全价电子晶体轨道研究的结果报告的糖磷酸链的DNA。的价和传导带宽被发现是足够大，使电子离域通过这个骨干可能。在DNA中的电荷载流子传输的不同机制进行了比较的基础上的电子和空穴的有效质量。沿着骨架的传导似乎至少和通过叠加的核苷酸碱基的非周期系统的传导一样可能。
The results of a CNDO/2 all‐valence electron crystal orbital study are reported for the sugar‐phosphate chain of DNA. The valence and conduction bandwidths are found to be large enough to make electronic delocalization through this backbone possible. Different mechanisms for charge carrier transport in DNA are compared on the basis of the electron and hole effective masses. Conduction along the backbone seems to be at least as probable as through the aperiodic system of the superimposed nucleotide bases.
