title: [Study on fluorescence spectra of the four heterocyclic compounds in solution].
abstract: The fluorescence spectra of the four compounds have been studied. Geometric configurations of the four compounds have been optimized by semi-empirical method RHF/AM1 of quantum chemistry. There is no imaginary frequency in vibrational analysis. Their fluorescence spectra have also been calculated by RHF/CIS. The results of calculation in solution are better agreement with experimental values than in gas phase.
