Small Molecule Structure Elucidation

CMC-se is a NMR software package for simple and efficient structure elucidation of small molecules.

With its innovative approach, CMC-se accelerates the spectroscopist’s workflow during the elucidation process by automating many of the key analysis and interpretation steps. In combination with Bruker’s AVANCE™ NMR spectrometer product line, CMC-se is the only elucidation tool that integrates high quality NMR data acquisition with sophisticated software analysis. CMC-se further expands its capabilities to full data set structure verification. The use of long range correlations adds an extra layer of confidence, producing results with maximum reliability.

CMC-se Classroom

For educational purposes, CMC-se is also available as a Classroom edition. It includes all the functions of the full version, with the exception of automatic structure generation and assignment. In addition, extensive supporting materials and training data sets may be downloaded here.

The Classroom edition is available only for academia, since March 1st 2019 is the CMC-se Classroom license integral part of Topspin for academia.


CMC-se is integral part of TopSpin installation, which may be downloaded here.
