A product operator formalism of 3D J-resolved NMR spectroscopy for ISnKm(I = 1/2, S = 1/2, K = 1/2) spin system

Abstract

Product operator formalism is widely used for analytical description of multiple-pulse NMR experiments for weakly coupled spin systems. 3D J-resolved NMR spectroscopy is widely used in order to resolve the chemical shift along one axis and spin-spin coupling parameters along the two other axis. In this study, product operator theory is used for analytical description of heteronuclear 3D J-resolved NMR spectroscopy for the ISnKm(I = 1/2, S = 1/2, K = 1/2; n = 1,2, m = 1,2,3) spin system.
