Absorption spectra of some liquids in the VUV
Absorption spectra and oscillator strengths have been determined for the liquids, benzene, toluene, hexafluorobenzene, tetramethylsilane, 2,2-dimethylbutane, and 2,2,4-trimethylpentane over a spectral range from 120 to 300 nm and compared with gas phase spectra. The effect of condensation manifests itself most obviously for transitions assigned to upper states of relatively large spatial extent or for transitions with a high spectral density of oscillator strength. Compensating effects, however, appear to mitigate the effect of condensation for both hexafluorbenzene and tetramethylsilane.
