Abstract

Dynamic nuclear polarization (DNP) NMR spectroscopy, a high-polarization method, is rapidly changing the landscape of what is possible in solid-state nuclear magnetic resonance spectroscopy. To date, there have been over 200 publications discussing high-frequency DNP NMR of solids with more than half being released within the past few years. Below we provide for researchers that may be interested in this high-sensitivity technique an introduction to high-frequency DNP NMR spectroscopy, including instrumentation, mechanisms, polarizing agents, and sample preparation. While there are many applications utilizing high-frequency DNP NMR, Part II will deal with recent advances in method development and applications to biomolecular solids and materials science.
