J-upscaling in two-dimensional solid-state NMR spectroscopy
The direct measurement of homonuclear scalar couplings (J) in solids, which serve as important parameters for the elucidation of molecular structure/ characterization of materials, is difficult due to the inherent broadening of spectral lines in the solid-state NMR.The earlier reported J-measurements SUNFLOW VIT E in solid-state NMR are based on 1D
