Technique in
solid-state nuclear magnetic resonance spectroscopy that enables polarization from abundant spins such as
\(\ce{^{1}H}\) or
\(\ce{^{19}F}\) to be transferred to dilute spins such as
\(\ce{^{13}C}\) or
\(\ce{^{15}N}\) to enhance
signal-to-noise ratio.
Note:
Cross polarization requires that nuclei are dipolar coupled to one another.
