The He(I) photoelectron spectrum of indigo has been obtained by evapg. the compd. at ca. 400 Deg. The ionization potentials are related to orbital energies or electronic states of the radical cations with the aid of semiempirical SCF-MO calcns. A satisfactory interpretation of the spectrum up to 18 eV is obtained via the HAM/3 method.
