Abstract:

The polarizations of the long wavelength electronic absorption bands of the molecules phenanthrene, biphenyl, fluorene, carbazole, dibenzofuran, and dibenzothiophen have been determined by the method of magnetophotoselection. Also, the polarizations of the next higher absorption bands have been estimated for phenanthrene, carbazole and dibenzothiophen. In general, the results agree with theory. The bands belonging to the heterocyclic molecules have been assigned to 1L sub a and 1L sub b designations on the basis of the polarization results. The results are discussed briefly. Author
