Brint, P. Tsekeris, A. Bolovinos, C. Kosmidis Title: The vacuum-ultraviolet absorption spectra of substituted p-benzoquinones Journal/Source: J. Chem. Soc. Faraday Trans., 2, 85 (3), 177-186, (1989); DOI: 10.1039/F29898500177 Data: diagram, table Energy/Wavelength range: 5 - 10 eV (~ 124 - 248 nm) Resolution: Temperature: ~ 350 K Temperature dependence: no Pressure/Concentration: Phase: vapor; solution (acetonitrile) pH: Comments: The vacuum-ultraviolet spectra of methyl-substituted p-benzoquinones are reported and, where possible, their Rydberg structure is analysed. The samples required heating to ca. 350 K in order to obtain sufficient vapour pressure in the sample chamber. The solution spectra were measured using carefully purified acetonitrile as solvent.
