WebNMR spectroscopy uses the inherent magnetic properties of specific atomic nuclei to reveal the structure, identity, concentration, and behaviour of molecules in solid or … WebSummary: NMR spectroscopy relies on detecting the precession rates of nuclear magnetic moments, which is sensitive to chemical environment. In HSQC, we let the magnetization sit with each nucleus for some amount of time, thus sampling the chemical environment of both nuclei. The result is a signal that we can plot on both proton and nitrogen ...
