## Abstract A pulse sequence (SELRESOLV) for the protonβdetected determination of longβrange C,H coupling constants is described. The 2D __J__(HH) resolved experiment with selective ^13^C excitation separates __J__(HH) from __J__(CH) couplings. Application is demonstrated using crotonaldehyde and Ξ²
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
