Determination of the polarizability and the dipole moment of anthracene derivatives

  • Published:
Acta Physica Academiae Scientiarum Hungaricae

Abstract

The difference of dipole moments between the excited and ground state was determined to be 1.9 and 1.8 Debye for 9-acetoxyanthracene and 10-phenyl-9-acetoxyanthracene from the frequency shifts of absorption and emission spectra. The polarizability of these two compounds is 36×10−24 and 54×10−24 cm3, respectively. The measured natural lifetimes are compared with those calculated from the absorption integral taking into account the effect of intermolecular interactions on the optical properties of dissolved molecules.
