TopSpin

Newest Version of the Industry Standard Software for NMR

TopSpin 3.0

Automated and Faster Analysis in Small Molecule and Biomolecular Research

Structure Elucidation - CMC-se

CMC-se™is a 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 necessary processing and interpretation steps.  In combination with Bruker’s AVANCE™ NMR spectrometer product line, CMC-se is the only elucidation tool that seamlessly integrates high quality NMR data acquisition and sophisticated software analysis.

Starting Spectra

The TopSpin software includes parameter sets for 1D and 2D NMR data to be used with the CMC-se software package.  These parameter sets have been designed to provide high quality data with minimal artifacts to work best with the automated data analysis features of CMC-se.
