An excess charge effect on the hydrogen bond O_A-H…O_B is examined with the valence bond method developed in the authors' recent paper. It is shown that the potential energy curve of the proton becomes to have two minima and the stretching frequency of the proton decreases with the increase of excess charges (lack of electrons on the proton donor atom O_A and excess on the acceptor atom O_B). Hydrogen bonds of a guanine-cytosine (G-C) base pair, i.e., N_8^c-H…O_<11>^G and N_1^G-H…N_1^G, are also studied. It is shown that an N-H…N type H-bond is apt to have a stable secondminimum of the proton potential as compared with N-H…O and O-H…O bonds, and the reason is discussed.
