The chemical shifts (d) of solvent signals observed for 1 H NMR and 13 C NMR spectra are listed in the following table. The multiplicity is shown in parentheses as 1 for singlet, 2 for doublet, 3 for ...

As a training set, we used 500,000 artificially generated 1 H NMR spectra. We used different base frequencies (from 80 to 800 MHz) to generate spectra, ...
