Ab-initio study of model guanine assemblies: The role of pi-pi coupling and band transport [PDF]
Physical Review B 65, 045104 (2002), 2001 Several assemblies of guanine molecules are investigated by means of first-principle calculations. Such structures include stacked and hydrogen-bonded dimers, as well as vertical columns and planar ribbons, respectively, obtained by periodically replicating the dimers.
