cross polarization

https://doi.org/10.1351/goldbook.08327
Technique in solid-state nuclear magnetic resonance spectroscopy that enables polarization from abundant spins such as A1A221H or A19A2219F to be transferred to dilute spins such as A13A2213C or A15A2215N to enhance signal-to-noise ratio.
Note:
Cross polarization requires that nuclei are dipolar coupled to one another.
