Attenuation of Double-Quantum Cross-Relaxation in Overhauser DNP

Ravi Shankar Palani – @rshankarpalani

The Overhauser Effect DNP observed in insulating solids doped with BDPA radicals is investigated comprehensively for the role of individual 1H nuclear spins in hyperpolarizing the bulk, prompting us to selectively eliminate the 1H spins experiencing dominant DQ cross-relaxation, thereby obtaining improved bulk enhancements.
