08373 IUPAC Gold Book - J-resolved spectroscopy 10.1351/goldbook.08373 08373 current acronym: J-RES 1 Two-dimensional nuclear magnetic resonance spectroscopy resolving chemical shift information in one dimension and spin-spin coupling in the second. J-RES exists as both homonuclear and heteronuclear variants. The homonuclear variant can generate homonuclear decoupled projection when processed with a tilt function.
