Instrumentation for high-field dynamic nuclear polarization and electron paramagnetic resonance spectroscopy

Abstract

The technique of dynamic nuclear polarization (DNP) to enhance the intrinsically low sensitivity of an NMR experiment has been around since the early 1950s. While the technique is not new, recent advances in microwave technology, mainly driven by new developments in telecommunication technology, magnet technology, and quasi-optics allow researchers to perform DNP experiments in a ground-breaking new way. In this review article, we will give an overview of the current state of modern instrumentation for DNP spectroscopy and its sister technique Electron Paramagnetic Resonance (EPR) spectroscopy.
