Heteronuclear Nuclear Magnetic Resonance (NMR) is a crucial analytical technique that helps researchers understand the structure and dynamics of molecules. This powerful spectroscopic method utilizes the nucleus of different atoms to provide valuable information about chemical environments and molecular interactions. Synonyms for Heteronuclear NMR can be described as cross-polarization (CP) NMR, heteronuclear correlation spectroscopy (HETCOR), or heteronuclear single quantum coherence (HSQC) spectroscopy. These interchangeable terms highlight the capability of Heteronuclear NMR to study the connectivity between different atoms within a molecule. With its versatility and wide range of applications in various scientific fields, Heteronuclear NMR plays an indispensable role in advancing our understanding of complex molecular systems.
