Exact Classification of NMR Spectra from NMR Signals
ICASSP 2024 - 2024 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)Nuclear magnetic resonance (NMR) spectroscopy is routinely used to study the properties of matter. Therefore, different materials can be classified according to their NMR spectra. However, the NMR spectra cannot be observed directly, and only the NMR signal, which is a sum of complex exponentials, is directly observable in practice.

NMR spectra of many systems governed by axially symmetric second rank tensor interactions exhibit P2(cos θ) dependence on the angle 9 between the symmetry axis and the externally applied magnetic field. For the so-called "powder samples" consisting of many randomly oriented domains the resulting spectrum is the superposition of contributions from each ...

With 100% natural abundance and a large magnetic moment, fluorine-19 NMR creates no problems in sensitivity. The range in chemical shifts is very wide over all, around 800 ppm, although most resonances of carbon-fluorine environments occur within a 300 ppm scan.

With 100% natural abundance, a spin of ½, and moderately large magnetic moment, phosphorus-31 falls into the class of ‘easy’ NMR elements. Its importance in biological processes is crucial, and in vivo measurements of 31P NMR spectra were introduced in section 7.9.
