Selective 1D 1H 13C 13C polarization transfer experiments for small organic molecules

Selective polarization transfer from proton to adjacent carbon was accomplished by either selective cross-polarization or selective refocused-INEPT. Magnetization was transferred in the subsequent step to remote carbons separated by one, two or three bonds. The acquired data were processed by a new symmetrization protocol resulting in the signal-to-noise ratio enhancement by a factor of √2. Copyright © 1999 John Wiley & Sons, Ltd.
