ACD/Structure Elucidator Suite: How It Works
ACD/Structure Elucidator Suite: How It Works

Are you doing everything you can with your structural data?

With ACD/Structure Elucidator Suite, scientists are able to perform rapid dereplication, advanced verification, speedily characterize structures using NMR and other techniques, and perform de novo elucidation for complex unknown structures.

With access to increasingly vast spectral libraries (including the PubChem database), Structure Elucidator Suite allows researchers to quickly find and verify chemical structures using experimental spectra, which have been previously identified (dereplication).

If a structure is not identified within the databases, scientists can then use the software to apply advanced algorithms and quantitatively evaluate the fit between a proposed structure and experimental spectra—even determining viable alternatives which may be a better match. The software includes a wide range of structure characterization and verification tools which are easily accessible.

For truly complex problems, Structure Elucidator Suite allows for de novo structure elucidation, generating a complete set of all structures which fit the correlations observed in the experimental data. It also supports the use of other analytical information to narrow down the structural possibilities—all helping to resolve structures more quickly and efficiently.
