Z. Dinya et al., PHOTOELECTRON (HEI) SPECTROSCOPY OF FLAVONOIDS AND THIOFLAVONOIDS .1.MOLECULAR-ORBITALS AND IONIZATION-POTENTIALS OF CHALCONE, AURONE, AND1-THIOAURONE, Croatica chemica acta, 66(2), 1993, pp. 255-263
Electronic structure of chalcone (1), aurone (2a) and 1-thioaurone (2b
) has been studied by measuring their HeI PE spectra and the interpret
ation of data has been performed by means of semiempirical molecular o
rbital calculations (PMO, HAM/3 and CNDO/S).
