The Watson–Crick A·T and G·C base pairs are not only electronically complementary, but also photochemically complementary.
The excited-state double proton transfer (ESDPT) mechanism in a model DNA base pair, 7-azaindole (7AI) dimer, has been debated over the years.
Understanding double proton transfer in rare tautomers and its implication in the promotion of spontaneous mutations in DNA base pairs.
Formation of an excited-state complex enables ultrafast photorelaxation of dark nπ* states in GC and HC base pairs.
Intense terahertz radiation was applied to trigger transient proton transfer in DNA base pairs through quantum simulation.
