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.

Evaluation of the Benefit and Informing Capability of 2D NMR Experiments for Structure Elucidation Using CASE Software

CASE has made huge progress since it was first introduced, and is now considered a reference tool for solving very complex structures. However, there is always the question on what type of 2D experiments should be recorded in order to efficiently solve the problem at hand. In this poster we will examine the effect of various 2D spectra on the elucidation time, illustrated by three different examples.

With over fifteen years of development, Structure Elucidator Suite is featured in more than 40 peer-reviewed articles on Computer-Assisted Structure Elucidation, a number which is always increasing. Click to see the complete list.

New Structure Elucidation Tutorials

To accompany the new book, "Computer-Based Structure Elucidation from Spectral Data", we have released a free downloadable tutorial software package* based on ACD/Structure Elucidator Suite. This software includes experimental spectra, allowing users to explore various CASE techniques, become familiar with the Structure Elucidator interface, and interact with the unique Molecular Connectivity Diagram.

*The software is free for educational use only, and does not import new analytical data/spectra or save results to a database.
