| Abstract: | The electronic absorption and fluorescence spectra of dibenzoylmethanatoboron difluoride (DBMBF2) in a number of polar and nonpolar solvents have been studied; the quantum yields and fluorescence lifetimes have been measured,
and the vibrational structure of the spectra has been analyzed. The equilibrium configuration parameters of DBMBF2 in the ground state have been determined by the DFT method. It has been found that there is only one stable conformation
of DBMBF2 in the ground state. |
