DNP Experiments using OVJ

(Overhauser) DNP-enhanced NMR experiments can be conveniently performed in OVJ. Here, OVJ not only controls the NMR hardware, but also the Brigde12 Microwave Power Source (MPS). From OVJ it is possible to:

• Control the power and frequency of the MPS
• Record the tuning dip of the microwave cavity
• Vary acquisition parameters (e.g. microwave power) automatically

In this section we demonstrate a couple of simple DNP experiments and how to incorporate automating the MPS control into OVJ pulse programs.
