Dear All,
It is our pleasure to announce that the 57th Global NMR Educational Tutorial will be given by Prof. Chandrasekhar Ramanathan, Darmouth College, USA on the topic:
“Room Temperature DNP via substitutional-nitrogen (P1) centers in diamond”
Abstract:
Electron spins in diamond have long coherence and relaxation times at room temperature, making them an exciting platform for EPR and DNP experiments under ambient conditions. In this talk I will describe our recent W-band DNP experiments using the substitutional nitrogen (or P1) defect to hyperpolarize the 13C spins in both single crystal and diamond powders. The DNP spectra measured in these samples show signatures of multiple mechanisms including the solid effect, the cross effect, the truncated cross effect and the Overhauser effect. I will discuss how variations in the microscopic environments of the spins could lead to these observations.
