The vapor-phase far-infrared, mid-infrared, Raman, ultraviolet and laser-induced fluorescence spectra of indan were analyzed. The ring-puckering and ring-flapping energy levels for the S0 ground state were reassigned using far-infrared spectra and Raman and dispersed fluorescence spectra of jet-cooled molecules. The flapping and puckering levels in the S1 electron excited state were assigned using fluorescence excitation spectra of jet-cooled indan and ultraviolet absorption spectra.
