A qualitative dichroism analysis has been made on chemical species produced from iodine in stretched sheets of polyvinyl alcohol. The absorption bands at 290 mμ and 360 mμ have been attributed to the bent triiodine ion, and the transition moments of these bands have been found to be parallel to each other. From the optical density ratio (<I>R<SUB>d</SUB></I>) curve, the presence of a hidden band at about 420 mμ has been pointed out, and the band has been assigned to the absorption by the linear triiodide ion. Three different chemical species are absorbed in the visible region. By comparing the <I>R<SUB>d</SUB></I> values, the numbers of iodine atoms in the respective species have been estimated.
