Abstract

We have studied the nature of electronic transitions in the UV spectra of 2,3-polymethylene-3,4-dihydro-4-quinazolones and their analogs. The results of LCAO MO quantum chemical calculations in the ZINDO/S approximation, taking into account configuration interaction, correlate satisfactorily with the positions of the bands in the experimental spectra of the studied compounds.
