Abstract
The present invention relates to methods of performing Nuclear Magnetic Resonance (NMR) spectroscopy adapted for a hyperpolarized sample. The methods comprise the steps of hyperpolarizing a sample using DNP, wherein at least a portion of the NMR active nuclei receives hyperpolarization; performing NMR spectroscopy on the sample with the use of sequences of rf-pulses, wherein the pulse sequences comprises at least two rf-pulses, either on the same nuclei or on different nuclei, and wherein the pulse sequence is adapted for a hyperpolarized sample; and analyzing at least two of the NMR spectra to obtain a characterization of the sample, or to obtain an interim result to be used in the NMR spectroscopy step.
