Low-temperature NMR experiments and molecular modeling have been used to characterize the conformational behavior of a covalently cross-linked DNA base pair model. The data suggest that Watson-Crick or reverse Watson-Crick hydrogen bonding geometries have similar energies and can interconvert at low temperatures. This low-temperature process involves rotation about the crosslink CH2{single bond}C(5′) (ψ) carbon-carbon bond, which is energetically preferred over the alternate CH2{single bond}N(3) (φ) carbon-nitrogen bond rotation.
