The 5-hydroxy-5-methylhydantoin (5-OH-5-Me-dHyd) is a nucleobase lesion induced by the action of ionizing radiation on thymine residue in DNA. In this study, we present the hydrogen bonding base pairs involving 5-OH-5-Me-dHyd bound to the four bases in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T). Full geometry optimizations have been performed for the studied complexes by MP2 method. The interaction energies were corrected for the basis-set superposition error (BSSE), using the full Boys–Bernardi counterpoise correction scheme. Hydrogen bonding patterns of these base pairs were characterized using NBO analysis and AIM analysis. According to the calculated binding energies and structural parameters, the stability of the base pairs decrease in the following order: 5-OH-5-Me-dHyd:G>5-OH-5-Me-dHyd:A>5-OH-5-Me -dHyd:C~5-OH-5-Me-dHyd:T.
