Swiss DNP Initiative

In the twenty-five years since the writing of these lines, many other fields of nuclear magnetism have begun to incorporate some form of DNP: solid state CP-MAS, liquid state MRI, biochemical NMR, metabolic MRS…

The necessary hardware is rather different for the “dissolution-DNP” method, used for MRI/MRS, and the “gyrotron-DNP” method, used in CP-MAS solid-state NMR.

A couple of specific molecules have been used to perform DNP via “photo-excited triplet states.” The hardware required for such experiment includes a quite powerful light source but it is in principle not necessary to work at very low temperature.
