A new experimental technique with a rotating analyzer is applied to polarization measurements of luminescence spectra. This method enables us to record the difference of the vertical and the horizontal polarization components (Iv-Ih) with a high sensitivity. The sum (Iv+Ih) and the individual components (Iv and Ih) can also be recorded simultaneously. The method is used to measure the polarized fluorescence spectra of coronene and 1,12-benzoperylene. In either case, the 0–0 band as well as the bands of totally symmetric vibrations are clearly distinguished from the vibronic bands induced via vibronic coupling due to some non-totally symmetric vibrations.
