COSY spectra show 3-bond coupling (from H-C-C-H), whereas HMQC shows a 1-bond coupling (just C-H). Take a look at n-hexylbenzene. There are lots of similar positions in this structure, …

Like HMQC, the HSQC experiment is a 2D heteronuclear chemical shift correlation map between directly-bonded (J -coupled) 1 H and X-heteronuclei (such as 13 C and 15 N). HSQC …

The HSQC (Heteronuclear Single Quantum Coherence) experiment is used to determine proton-carbon single bond correlations, where the protons lie along the observed F2 (X) axis and the …
