Mnova StereoFitter

An advanced tool for 3D conformational and configurational analysis using experimental constraints from NMR spectra

Mnova StereoFitter computes the probability of 3D structural configurations and/or conformations, based on various forms of NMR experimental data input. Currently, StereoFitter can accept four distinct types of input in order to calculate the best 3D structure candidate(s): NOEs, RDCs, Js, and chemical shifts.

A license of Mnova NMR (version ≥14.1.1) is required for Mnova StereoFitter!

  • Results are presented in order of best fit
  • Various formats of external structure files are compatible: SDF; XYZ; MAE
  • Chemical shifts can be computed within StereoFitter using DFT

Mnova StereoFitter


  • 3D conformations can be calculated from the 2D structure
  • Sets of 3D conformations can be interactively viewed, aligned, overlayed, and filtered by energy level
  • Stereoisomers can be computed from any 2D structure with ambiguous stereo centers
  • All types of measured constraints can be used in one 3D calculation for more accuracy and precision

For NOEs, distances are easily calculated from measured cross-peak volumes with a single click.

You can find an example in the manual (p.27) of Mnova StereoFitter using NOEs to determine 3D structure from a set of conformers.

For RDCs, automatically calculate RDC values from isotropic and anisotropic spectra.

You can find an example in the manual (p.35) of Mnova StereoFitter using RDCs and predicted chemical shifts to determine 3D structure from a set of stereoisomers.

For chemical shift prediction, DFT calculations can be carried out within StereoFitter. A separate DFT Predictor license is required for running these calculations. The DFT Predictions section of the ribbon contains tools to predict 1H or 13C chemical shifts using results from a server-based DFT

You can find more information in the manual (p.24)
