Abstract
Polarization of the fluorescence of alcohol and glycerine solutions of phthalimides was studied over a wide temperature range as a function of the wavelength of the exciting light. The maximum polarization reaches nearly 50% at sufficiently low temperatures and with long-wave excitation. There is a discussion of the possible sensitivity of the P = f(v exc) dependence to overlap of the first and second absorption bands and to the duration of the excitation at various exciting wavelengths.
