The selective ge-1D HSQC-COSY experiment affords a simple 1D 13C-edited COSY spectrum in which the protons directly-bonded to the selected carbon appear as large doublet due to 1JCH and the protons J-coupled with them show the commonly anti-phase pattern of COSY signals.

2017年1月9日 · A user-friendly NMR interface for the visual and accurate determination of experimental one-bond proton-carbon coupling constants (1 J CH) in small molecules is presented. This intuitive 1 J CH profile correlates directly to δ( 1 H), and 1 J CH facilitates the rapid identification and assignment of 1 H signals belonging to key structural ...
