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 in solid-state NMR are based on 1D/ pseudo 2D spin echo modulation techniques. https://thecookiecountesses.shop/product-category/meringue-powder/
