Customized Metabolomics Database for the Analysis of NMR 1H–1H TOCSY and 13C–1H HSQC-TOCSY Spectra of Complex Mixtures [PDF]
[Image: see text] A customized metabolomics NMR database, termed (1)H((13)C)-TOCCATA, is introduced, which contains complete (1)H and (13)C chemical shift information on individual spin systems and isomeric states of common metabolites. Since this information directly corresponds to cross sections of 2D (1)H–(1)H TOCSY and 2D (13)C–(1)H HSQC-TOCSY ...

Interpretive Library Search of Plant Compound Spectra in a 13C NMR Database# [PDF]
The derivation of structural characteristics of a compound of unknown structure from its spectral data is a central procedure for modern structure elucidation. Computer searching in spectral libraries of fully-assigned 13C NMR spectra of substructures or full structures is an essential part of structure elucidation and has been widely applied because ...
