As mentioned above, pulsed DNP is still in its infancy and is mostly limited to experiments at X-band and Q-band. However, in experiments reported here at 94 GHz, we achieved e=496, which is presently a record enhancement for this frequency and temperature. Thus, we believe that our experimental results at W-band are compelling evidence that coherent DNP methods are extremely promising approaches for spectroscopy at higher fields, where the resolution of NMR spectra is optimized. Accordingly, it is important to develop the instrumentation and expertise to explore and develop these methods further.
