Webb13 juli 2024 · Based on the Kasha theory , one expects a formation of two states out of each monomeric excited state (see Equation ). In particular, two n π * states corresponding to the S 1 state of azobenzene and two π π * states corresponding to the S 2 state of azobenzene are expected in the low energy region of the azobenzene dimer spectrum.
