| Abstract | Solvent shifts of the energies of the lowest /sup 1/L/sub a/ bands of the electronic absorption spectra of anthracene, chrysene, phenanthrene, and tetracene and of the lowest /sup 1/L/sub b/ bands of the electronic absorption spectra of naphthalene, phenanthrene, chrysene, and picene are reported. The origins of these shifts are analyzed in terms of theories developed by Baur and Nicol and by Abe. Satisfactory fits of the experimental data are obtained for theoretical expressions derived from both theories, but discrepancies are observed between the relative magnitudes assigned to the various contributions to the shifts by the two theories. The magnitudes of the parameters of the Baur and Nicol theory, relating solvent shifts to the dielectric constant and refractive index of the solvent, are found to be the same within experimental precision for the /sup 1/L/sub a/ transitions in all of the molecules studied; a similar regularity of the parameters for the /sup 1/L/sub b/ transitions also is observed. |
