However, the opposite behaviors are true for the ionization potentials and the singlet-triplet energy gaps of uracil monomer and its dimer, suggesting that thiouracils are more susceptible to radiation damage through the loss of an electron relative to the unsubstituted uracil. Additionally, for U::U and SU::SU base pairs, the influences of both ionization and excitation on the hydrogen bond involving sulfur substituent directly are more significant than those without substitution.
