Electronic coupling in the excited electronic state of stacked DNA base homodimers.
The nature of the electronic coupling of stacked nucleic acid bases adenine (A), thymine (T), and cytosine (C), in A-A, T-T, and C-C complexes in their excited states was investigated; a different character of the electronic coupling for the T-T complex was shown.
