The sharp-line absorption spectra (full width at half-maximum of 1 to 10 cm/sup -1/) exhibited by polynuclear aromatic hydrocarbons (PAHs) in frozen Shpol'skii hosts facilitate selective excitation of the luminescence spectra through tunable dye laser excitation. In this communication we present observations that document the general utility of laser-excited Shopol'skii spectroscopy (LESS) for the direct qualitative and quantitative characterization of complex mixtures of PAHs, including multialkylated isomers.
