Abstract
Methods and systems for Nuclear Magnetic Resonance (NMR) spectra of complex chemical mixtures are described. The methods and systems allow undesired NMR spectral background to be removed or suppressed and target spectral peaks to be uncovered, for example, when strong background signals overlap weaker peaks. In some embodiments, the methods and systems employ a quantum filter utilizing nuclear spin singlet states.
