Optical and dielectric functions of liquid methylated benzenes in the 2- to 10-eV spectral region

Abstract
The optical and dielectric functions have been determined in the 2 to 10-eV spectral region for four polycyclic hydrocarbons: benzene, toluene, xylene, and trimethylbenzene. The effect of substitution on the spectra of these liquid alkyl benzenes is investigated and comparisons are made to the appropriate gas-phase spectra.
