Charge transfer from O1 to O2 of 3HFN results in proton H1 transfer from O1 to O2 in S1 state, while small energy barrier facilitates proton H1 transfer from O1 to N1 in S1 state of diCN-HBO, which results in charge transfer from O1 to di-cyano.

Oxidation Processes

The effect of change of solvent on the positions and intensities of absorption bands of some aromatic amines between 200 and 400 nm has been examined. In particular, the behavior of the band at 280 nm has been studied.In hydroxylic solvents, this band is displaced towards shorter wavelengths, and the dipole moment in the excited state of the molecule is smaller than in the ground state. The opposite effects are found when nonhydroxylic solvents are used.The results show how the molecular structure is altered by charge transfer effects and can explain how different solvents affect photochemical oxidation processes.
