Enumeration of atoms (right above) in the Fl derivatives (numbered 1–4). In the rectangle (right below) shown is position of the ground, S0, and three excited–state equilibrium forms: S1LE(π,π*), S1LD(n,π*), and S1LU(n,π*) for 1, in the [R1, R2] configuration space. Molecule 1 is 10-butyl-3-methyl-7-(3,4,5-trimethoxyphenyl)isoalloxazine, molecule 2 is 3,10-dimethyl-7-(3,4,5-trimethoxyphenyl)isoalloxazine, molecule 3 is 3,10-dimethyl-7-phenylisoalloxazine, molecule 4 is 3,10-dimethylisoalloxazine.
