| description | <p>This thesis describes the construction of a very versatile broadline 10-100MHz frequency swept nuclear magnetic resonance spectrometer equipped with a 50 kilogauss superconducting magnet.</p> <p>Measurements have been made, using this spectrometer, to obtain chemical shifts of the <sup>133</sup>Cs ion to high precision and to very low concentrations (.005<em>M</em>) in aqueous and non-aqueous media. Remarkable effects have been observed and a theory is proposed that can predict the ion-ion contribution to the chemical shift in solution.</p> <p>Chapter 1 describes the n.m.r. experiment and discusses factors affecting the signal to noise ratio that are relevant for the construction of the spectrometer.</p> <p>Chapter 2 gives a brief description of the properties of the superconducting materials used to wind the magnet for the spectrometer and describes the construction and handling of the magnet and its related components.</p> <p>Chapter 3 describes experiments made on the superconducting magnet to determine and improve its homogeneity.</p> <p>Chapter 4 gives an account of the construction of the spectrometer and cites examples of its performance.</p> <p>Chapter 5 outlines a theory proposed by Dr. R.R. Sharp of this research group to interpret the cesium chemical shifts observed.</p> <p>Chapters 6 and 7 describe the measurements of cesium chemical shifts in aqueous and non-aqueous media. These shifts are interpreted in terms of the theory proposed in chapter 5.</p> <p>The Appendix contains the raw experimental data obtained for this thesis.</p> |
