  • CREATION OF NEARLY-EQUIVALENT NUCLEAR SPIN SINGLET STATES USING SPIN-LOCK INDUCED CROSSING
    Publication number: 20190072628
    Abstract: Methods and systems for Nuclear Magnetic Resonance (NMR) spectra of samples having unresolved peaks are described. The methods and systems allow for the creation nuclear spin singlet states in nearly-equivalent spin pairs, for example, using continuous spin-locking with a nutation frequency matched to the coupling strength between spins.
    Type: Application

  • Creation of nearly-equivalent nuclear spin singlet states using spin-lock induced crossing
    Patent number: 10101423
    Abstract: Methods and systems for Nuclear Magnetic Resonance (NMR) spectra of samples having unresolved peaks are described. The methods and systems allow for the creation nuclear spin singlet states in nearly-equivalent spin pairs, for example, using continuous spin-locking with a nutation frequency matched to the coupling strength between spins. The invention relates generally to the field Nuclear Magnetic Resonance (NMR). Nuclear magnetic resonance (NMR) spectroscopy can be used as a tool for determining the chemical structure and/or geometry of a molecule in a sample. In many samples, however, resonance frequencies of different nuclei fully or partially overlap, which makes chemical identification of molecule(s) in a sample difficult or impossible.
    Type: Grant

    Date of Patent: October 16, 2018
    Assignee: President and Fellows of Harvard College
    Inventors: Stephen J. Devience, Ronald L. Walsworth, Matthew S. Rosen
  • Nuclear singlet states as a contrast mechanism for NMR spectroscopy
    Patent number: 9804239
    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.
