摘要：

In NMR, a coupled I and S spin system can interchange polarizations by J-cross polarization (JCP). If the S spectrum is observed without I decoupling, the relative phases of the lines within the S multiplet vary with cross-polarization time. A PCJCP sequence (phase corrected J-cross polarization) is demonstrated which removes the phase variation; this facilitates determination of the spin coupling constant J directly from the cross-polarization spectrum. © 1979, American Chemical Society.
