Synopsis:

This book details constructional information for a Nuclear Magnetic Resonance (NMR) spectrometer using the natural magnetic field of the Earth as B0, and presents experiments exploring the impressive range of concepts and techniques which can be demonstrated with such a machine. These include the Free Induction Decay, T1 and T2 time constants, spin echoes with 90 degree and 180 degree B1 pulses, and the effects of B0 field inhomogeneity and shimming. Although chemical shifts of parts per million in spectral line frequency cannot be resolved, the splitting of lines by heteronuclear J-coupling is clearly displayed. The machine can make geomagnetic measurements accurate to 5 significant figures. And it can demonstrate the core principle of Magnetic Resonance Imaging: the encoding of spatial information in the phase and frequency domains using the Pulsed Gradient Spin Echo sequence.
