We determined the effective electric dipole moment difference DELTA-mu* of perylene in the amorphous polymer polyvinylbutyral from the changes of persistent spectral holes in an external electric field. The value of DELTA-mu* increases with increasing wavelength of the spectral hole in the inhomogeneous absorption band. The experimental results are compared with calculations of the wavelength dependence of DELTA-mu* using an extension of the theory of pressure broadening and shift of spectral holes of Laird and Skinner [J. Chem. Phys. 90, 3274 (1989) ]. The calculations are based on changes of the matrix shift of perylene by the electric field. Best agreement between the calculations and the measurements was obtained when changes of a short-range intermolecular interaction, like the repulsive interaction, by the electric field were assumed to be dominant.
