WebFast and accurate prediction of 13 C and 1 H NMR spectra from the molecular structure plays an important role in structure validation and elucidation of molecules. The NMR … WebHerein, we report a computational algorithm that follows a spectroscopist-driven elucidation process of the structure of an organic molecule based on IR, 1H and 13C NMR, and MS tabular data. The algorithm is independent from database searching and is based on a bottom-up approach, building the molecular structure from small structural fragments …
