Optically-generated Overhauser dynamic nuclear polarization: A numerical analysis

Autor: Christopher J. Wedge, Daniel J. Cheney

Publikováno v: The Journal of chemical physics. 152(3)

Recently, an alternative approach to dynamic nuclear polarization (DNP) in the liquid state was introduced using optical illumination instead of microwave pumping. By exciting a suitable dye to the triplet state which undergoes a diffusive encounter
