## Abstract Known selective 2D Jโresolved methods for the determination of longโrange protonโcarbon coupling constants, ^n^__J__(C, H), have been modified and improved by introducing an INEPT or refocused INEPT sequence as a preparation period in the BaxโFreeman selective spinโflip method, or using
In recent years, heteronuclear J cross-polarization experi-pled proton(s) via 1 H-1 H NOE when the source carbon is ments have been revitalized as a preferable alternative to protonated (13). Both selective one-dimensional and nonsetechniques based on pulse-interrupted free precession to lective mul
Chiral synthons containing either 13Cor 15N-labelled glycine were prepared. The 13C and 15N NMR spectra of the Ni(II) complex of the Schi โ base of (S)-2-(N-benzylprolyl)aminobenzophenone and 13C-1-, 13C-2or 15N-labelled glycine were measured and assigned. The observed splitting of the carbon signal
