The hole truth: A low-energy band in the absorption spectrum of the oxidized Watson–Crick complex of guanosine and cytidine derivatives (see scheme) is attributed to charge-transfer localizing the hole from one-electron oxidation on the cytidine moiety. The band provides an estimate of the energy of one of the low-lying electronic states of oxidized duplex DNA.
