✦ Synopsis
The fluorescence excitation spectra of a number of furan-based scintillation compounds, including 25diphenylfuran (PPF), have been measured under jet-cooled conditions.
While many of the species are effectively planar, steric crowding is found to force diphenylisobenzofuran into a non-planar ground state, so that two rotameric forms are observed. The molecule PBD is also found to be non-planar, consistently with literature data for biphenyl itself. Finally, evidence of torsional mode coupling is observed for a-naphthyl-substituted compounds.
