An anisotropic Lorentz field approximation was used to obtain the local field from the macroscopic $field.^{1,2}$. Other $interactions^{3}$ in the crystal can contribute significantly to the Stark splitting, and many of these have been ignored in previous analyses of such Stark effects. By explicitly including, in a self-consistent way, the many contributions that can arise from guest and host dipole-dipole and dipole-electric field interactions, an improved analysis of the Stark splitting in the spectra of a polar impurity isolated in a nonpolar host crystal is obtained in closed $form,^{4}$ within the context of the point dipole approximation. This analysis results in a second rank tensor that couples the molecular dipole moment change to the macroscopic electric field. This tensor will be compared with that obtained from the Lorentz local field analysis. en_US dc.format.extent 175447 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title THE ORIGIN OF STARK SPLITTINGS IN MOLECULAR CRYSTAL SPECTRA en_US dc.type article en_US
