电子解耦 MAS DNP 与 N@C(60)

Abstract

Frequency-chirped microwaves decouple electron- and (13)C-spins in magic-angle spinning N@C(60):C(60) powder, improving DNP-enhanced (13)C NMR signal intensity by 12% for 7 s polarization, and 5% for 30 s polarization. This electron decoupling demonstration is a step toward utilizing N@C(60) as a controllable electron-spin source for magic-angle spinning magnetic resonance experiments.
