Abstract
A solution of an aromatic amine in a saturated hydrocarbon is cooled in liquid nitrogen to a clear, rigid state, and an electron is ejected from the amine with polarized ultraviolet light. Recombination may be stimulated by infrared light, resulting in the emission of polarized recombination luminescence. An experiment will be described which was designed to use this phenomenon to find out whether (1) the ejected electrons remain so close to the molecules they came from that they return to their individual sites of origin, or (2) they are ejected so far that they lose all correlation with their original molecules, and generally recombine at a site different from the one they left. The results are clear-cut, and confirm (1). However, photoconductivity accompanies the recombination, and a more complicated interpretation of the result is demanded.
