NMR spectroscopy is highly sensitive as compared to conventional NMR spectroscopy, and may be applied for several elements across the periodic table. β - NMR has previously been applied successfully in the fields of nuclear and solid state physics. In this work β - NMR is applied for the first time to record an NMR spectrum for a species in solution. 31 Mg β - NMR spectra are measured for as few as 10 7 magnesium ions in ionic liquid (EMIM - Ac) within minutes as a prototypical test case. Resonances are observed at 3882.9 kHz and 3887.2 kHz in an external field of 0.3 T. The key achievement of the current work is to demonstrate that β - NMR is applicable for analysis o f species in solution, and thus represents a novel spectroscopic technique in general chemistry and potentially in biochemistry.
