In this work, we investigate the mode of binding of all nine hydrogen-bonded structures of the adenine • • • thymine base pair. The planar H-bonded structures were optimized at the MP2/cc-pVTZ level, and the respective interaction energies, corrected for the basis set superposition error, were determined with the aug-cc-pVDZ basis set. The energy components were obtained from the DFT-SAPT procedure using the aug-cc-pVDZ basis set. The charge-transfer character of the single structures was estimated using NBO characteristics.
