The polarization of fluorescence excitation and emission bands of all-nuns retinol in ether at 77Β°K has been measured at relatively high resolution. 7?le main escitation band as well as the fluorescence band showed a degree of polnrization approaching that of the theoretical maximum of 0.5 for a lin
