Скачать или смотреть Overhauser Dynamic Nuclear Polarization in the Liquid State | Marcel Levien | Session 40

During the 40th session of the Global NMR Discussion Meetings held on December 7th, 2021 via Zoom, Marcel Levien, Ph.D. student in Prof. Marina Bennati's laboratory at Max Planck, Göttingen, Germany, gave a talk on "Overhauser Dynamic Nuclear Polarization in the liquid state at room temperature at low and high magnetic fields". The recording serves as a tutorial.

Abstract:
Dynamic Nuclear Polarization (DNP) is a tool that promises to overcome the long-standing sensitivity issues in modern Nuclear Magnetic Resonance (NMR). While it is already commercially available in the solid-state, in the liquid state at room temperature the development at high magnetic field is still in its infancy. However, recent advances in the understanding of the polarization transfer mechanisms and in the hardware technology demonstrate the viability of DNP in liquids at high magnetic fields. During this talk, the general Overhauser mechanism for the liquid state will be discussed. Particularly, the polarization transfer via scalar interaction, its frequency dependence as well as the role of the polarizing agent will be explained. Finally, an overview about recent applications at low field as well as developments at high magnetic field will be given.
