This thesis investigates the nuclear magnetic resonance in a crystalline stable free radical.

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.

It is shown that light emitted by mercury vapour at 253.7 nm can be polarized by passing the light through mercury absorption gas embedded in a magnetic field which is transverse to the direction of propagation of the light. The absorption lines of the mercury are split by the Zeeman effect, so that the absorber has an absorption coefficient which depends on both the polarization and wavelength of the transmitted light. A complete theory for the Hg²⁰² isotope is presented and the results are compared to measurements made with a natural mercury emitter and absorber. The observations are in qualitative agreement with the theory once isotope and hyperfine structure of the isotopes in natural mercury are included in the theory. Quantitative analysis was not possible because the emission line profiles could not be measured with the available equipment. / Science, Faculty of / Physics and Astronomy, Department of / Graduate
