STUDIES IN CRYSTAL SPECTRA.
Abstract
In the solid state the absorbing units are arranged in a regular array, and by using polarized light, the polarization properties of the absorptions may be determined. With a prior knowledge of the detailed structure of the crystal and the crystal spectra results one then knows considerably more about the energy levels, intensity mechanisms, and other interactions than solution data can afford. The method is also useful for the study of complexes which exist only in the solid state. A series of bivalent nickel complexes was studied. The crystal structures of many nickel compounds are well known and they are easy to prepare. Complexes of bivalent nickel are also ideal for study since the theory of the electronic transitions is well established and the ion is free from complicating distortions such as the Jahn-Teller effect. The investigation was extended to include the square planar nickel complexes and cis-cobalt complexes because of a general lack of knowledge of these systems. (Author)
