A theoretical application of 3D J-resolved NMR spectroscopy for ISnKm (I=1/2, S=1/2 and 1, K=3/2) spin systems

Abstract

In 3D J-resolved NMR spectroscopy, the chemical shift along one axis and the spin-spin coupling parameters along the two other different axes are resolved. Product operator theory is used for the analytical description of multi-dimensional NMR experiments on weakly coupled spin systems. In this study, the product operator description of heteronuclear 3D J-resolved NMR spectroscopy of weakly coupled ISn K-m (I = 1/2, S = 1/2 and 1, K = 3/2) spin systems is presented.
