Description
Ravi Palani and co-authors review how spinning samples boost weak nuclear magnetic resonance signals in this 2026 paper. NMR reveals molecular structure, but its faint signals limit what it can see. Dynamic nuclear polarization lends nuclei the far stronger pull of electron spins. Spinning the sample at a magic angle then sharpens the signal into readable detail.
The review walks through the main transfer methods and how each scales with field strength, spin rate, and microwave power. It traces polarizing agents from early two-radical designs to newer asymmetric ones that hold up past eighteen tesla. Instruments, pulsed methods, and applications in biology, materials, and surfaces round out the survey.
