WebYou will see your 1H spectrum as your direct F2 axis and your 13C chemical shifts as your indirect F1 axis. Any observed cross-peaks indicate protons that share multiple bond long-range J-coupling with carbons, say in the range of 3-10 Hz. 7-8 Hz is a great choice when setting your target long-range J-coupling constant. WebThe heteronuclear single quantum coherence or heteronuclear single quantum correlation experiment, normally abbreviated as HSQC, is used frequently in NMR spectroscopy of organic molecules and is of particular significance in the field of protein NMR.
