Optically generated hyperpolarization for sensitivity enhancement in solution-state NMR spectroscopy.

Published in: Chemical communications (Cambridge, England) (2018)

We show that optical excitation of radical triplet pair systems can produce a fourfold NMR signal enhancement in solution, without the need for microwave pumping. Development of optical hyperpolarization methods will significantly impact all NMR user groups by boosting sensitivity and reducing signal averaging times.
