Perspectives on DNP-enhanced NMR spectroscopy in solutions

Perspectives on DNP-enhanced NMR spectroscopy in solutions

van Bentum, J., et al., Perspectives on DNP-enhanced NMR spectroscopy in solutions. J Magn Reson, 2016. 264: p. 59-67.

More than 60years after the seminal work of Albert Overhauser on dynamic nuclear polarization by dynamic cross relaxation of coupled electron-nuclear spin systems, the quest for sensitivity enhancement in NMR spectroscopy is as pressing as ever. In this contribution we will review the status and perspectives for dynamic nuclear polarization in the liquid state. An appealing approach seems to be the use of supercritical solvents that may allow an extension of the Overhauser mechanism towards common high magnetic fields. A complementary approach is the use of solid state DNP on frozen solutions, followed by a rapid dissolution or in-situ melting step and NMR detection with substantially enhanced polarization levels in the liquid state. We will review recent developments in the field and discuss perspectives for the near future.
