摘要
(Figure Presented) Double or nothing: Large-scale density functional calculations are used to study the formation of a large polaron on three proximal guanines (see picture). The formation was observed by step by step following of a proton-coupled charge transfer. The role played by the double proton transfer and a new and unexpected role for the tautomers of G and C were found. © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
