Effect of ring torsion on intramolecular vibrational

The role of ring torsion in the enhancement of intramolecular vibrational energy redistribution (IVR) in aromatic molecules was investigated by conducting excitation and dispersed fluorescence spectroscopy of 1 1′-binaphthyl (1 1′-BN) and 2 2′-BN The dispersed fluorescence spectra of 1 1′-BN in the origin region of S 1 –S 0 were well resolved which presented 25–27 cm −1 gaps of
