Dynamic Nuclear Polarization (DNP) is often achieved by the direct transfer of polarization from electrons to nuclei such as C-13, induced by microwave saturation of the wings of narrow EPR lines of radicals like trityl. In the indirect approach on the oth ...
Since many biological processes occur on the μs to ms time scale, internal dynamics on that time scale is believed to be related to biological functionality. The characterization of internal dynamics is thus an important issue to improve our understanding ...
