Abstract Vibronic spectra of 1, 1′-binaphthyl in pentane Shpolskii matrices at 4 K are reported. Taken in conjunction with the IR and Raman spectra, it can be seen that these arise from two non-interconverting ground-state conformers. The fluorescence origins of these conformers are split by 4850 cm−1. A vibronic analysis suggest that the two naphthalene moieties are approximately perpendicular in the conformer with the higher-energy origin, while being approximately planar in the other. The absence of progressions in the torsional mode in the spectra of each conformer suggests that their conformations are unaltered in the excited state. Spectra in other media suggest that the two ground-state conformers also exist in many liquid solutions.
