Figure 1.
Singlet excited-state transitions of B-form 5′2AP-T as determined by TDDFT [B3LYP/6-311 + G(d)]. Jablonski diagrams for both monomer and dimer are shown. Oscillator strengths are shown in parentheses as are the dominant one-electron orbital contributions for the dimer transitions. Orbital amplitudes for the HOMO-1, HOMO and LUMO, LUMO + 1 are shown. The widths of the lines denoting the excited-state transitions reflect the relative oscillator strengths of the monomer and dimer transitions.
