In the first part of this thesis, experiments utilizing an NMRphase interferometric concept are presented. The spinor character oftwo-level systems is explicitly demonstrated by using this concept.Following this is the presentation of an experiment which uses thissame idea to measure relaxation times of off-diagonal density matrixelements corresponding to magnetic-dipole-forbidden transitions in a^(13)C-^1H, AX spin system. The theoretical background for these experimentsand the spin dynamics of the interferometry are discussed also.
The second part of this thesis deals with NMR dipolar modulatedchemical shift spectroscopy, with which internuclear bond lengths andbond angles with respect to the chemical shift principal axis frameare determined from polycrystalline samples. Experiments using benzeneand calcium formate verify the validity of the technique in heteronuclear(^(13)C-^1H) systems. Similar experiments on powdered trichloroaceticacid confirm the validity in homonuclear (^1H- ^1H) systems. Thetheory and spin dynamics are explored in detail, and the effects of anumber of multiple pulse sequences are discussed.
The last part deals with an experiment measuring the ^(13)C chemicalshift tensor in K_2Pt(CN)_4Br_(0.3) • 3H_2O, a one-dimensional conductor. The^(13)C spectra are strongly affected by ^(14)N quadrupolar interactions viathe ^(13)C - ^(14)N dipolar interaction. Single crystal rotation spectra areshown.
An appendix discussing the design, construction, and performanceof a single-coil double resonance NMR sample probe is included.
