Abstract:
A compound is identified by matching its proton and/or carbon NMR spectra to NIH PubChem molecular structures. The matching process involves analyzing 1D proton, 1D carbon, DEPT, and/or HSQC spectra, and comparing the number of NMR resonances, detected proton and carbon shifts, likely number of methyl- and methoxy-groups, and an optionally specified molecular formula to predicted proton and carbon shifts of PubChem structures. A structure verification module rates the consistency between experimental spectral analysis results and a proposed structure (not limited to PubChem structures) and assigns observed shifts to the proposed structure. The spectral analysis, structure identification, and structure verification are largely automated in a software package and can be performed in minutes.

While α protons of carboxylic acids absorb at 2–2.5 ppm, β protons absorb further upfield.
Carboxylic acids are easily identified by dissolving them in deuterium oxide, which results in a rapid exchange of the acidic protons with deuterium. This leads to the disappearance of the acidic...
