Magnetic Resonance at or Below the Earth's Magnetic Field
Christina M. Thiele
NMR resonances of two nuclei can be obtained in one spectrum at ultralow magnetic fields. At such low fields, chemical shifts become negligible and heteronuclear couplings dominate the NMR spectra. The Highlight gives an overview of pure J-coupling spectroscopy and (functional) imaging applications at magnetic-field strengths in the range of the Earth's magnetic field.
