• We measured the polarized absorption spectra of the γ-hydroquinone and 1,4-dimethoxybenzene crystals in the wave number region between 30000 cm<SUP>−1</SUP> and 65000 cm<SUP>−1</SUP>. The dichroic ratios determined for the spectra of both crystals show that the bands at ∼290 nm and at ∼220 nm are polarized parallel with the short and long molecular axes, respectively; these support the assignment that they correspond to the L<SUB>b</SUB> and L<SUB>a</SUB> bands of benzene, respectively. The dichroic ratios and intensities determined for the bands in the vacuum ultraviolet region show that they do not simply correspond to the B<SUB>a,b</SUB> bands of benzene and that mixing among appropriate excited states occurs in both crystals.
