This thesis project has involved a study of forbidden radiation: a phenomenon studied in the discipline of Atomic Spectroscopy. Specifically, the forbidden spectral line 6647 A of Hg II was examined. This line is of mixed multipolarity in that it is composed of magnetic-dipole and electric-quadrupole radiation. Emission of these two multipolarities gives rise to an interference effect which is quite useful in determining the degree to which each multipolarity contributes to this forbidden line.The results of the study carried out here agree with the theoretical predictions made for this line. They indicate that less than two percent electric-quadrupole radiation is present in the line. This study of the interference effect demonstrates the importance of obtaining both the transverse and longitudinal views of the line relative to the direction of the magnetic field. Both views, it is felt, are necessary for experimental verification of the line's structure.
