  • NMR J-couplings

    2019-10-17 · NMR J-coupling or nuclear spin-spin coupling is an indirect interaction of the nuclear magnetic moments mediated by the bonding electrons. It is manifested as the fine structure in NMR spectra, providing a direct measure of bond strength and a map of the connectivities of the system. The J-coupling mechanism is an essential component of many NMR ...
