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.
