Nuclear magnetic resonance (NMR) spectroscopy is a technique that detects the chemical environment of atomic nuclei by the absorption of radio-frequency electromagnetic radiation when in the ...

However, elucidating structure using only one-dimensional (1D) NMR spectra, the most readily accessible data, remains an extremely challenging problem because of the combinatorial explosion of the ...

Illustrative examples are the extraction of 3,4-dihydroxy benzoic acid, caffeic acid, vanillic acid, and syringic acid from date seeds obtained from an optimized process based on ChCl:lactic acid 1:2 ...
