title: Electronic structure of coumarins.
abstract: The electronic structure of coumarin derivatives has been investigated by a combination of UV photoelectron spectra (UPS), semi-empirical MO calculations and comparison with the spectra of related coumarins. The influence of substituents on the S0 and S1 electronic states energies is discussed.
