How it Works

NMR Predictions in a Few Simple Steps

  1. Import a structure from a file, or draw the molecule(s) in the interface
  2. Define the experimental conditions (field strength, concentration, solvent, etc.)

     
  3. Calculate full 1D and 2D NMR spectra, chemical shifts, and coupling constants for the structure(s)
  4. Compare the predicted spectrum with the experimental spectrum
  5. Add new structures to your own database to further improve the accuracy for novel compounds

Features of NMR Predictors

    General
    • Predict spectra for structures, whole polymers, peptides, and mixtures
    • Predict NMR spectra by drawing the chemical structure or importing it from a variety of formats (including SDFiles, molfiles, SMILES, InChI, etc.)
    • Dual prediction algorithm—neural network and HOSE code algorithms
    Predict NMR Spectra

    Predict 1D NMR Spectra

    • Calculate NMR chemical shifts and scalar coupling constants for 1H, 13C, 15N, 19F, and 31p nuclei from structure
    • Predict fully decoupled 1H NMR (Pure Shift) spectra and/or consider second-order coupling effects

    *Databases sold separately

    Train the Algorithms
    • Improve prediction accuracy by adding experimental chemical shifts to the prediction database
    NMR Data Processing & Analysis
    • Perform manual and/or automatic NMR data processing: Fourier transformation, calibration, peak picking, integration, multiplet analysis, etc.
    • Accelerate spectral analysis and interpretation:
      • Attach chemical structures to a spectrum for real-time visual feedback on peak/atom assignments
      • Easily evaluate spectrum/structure consistency using quantitative NMR Match Factor values
    • Use powerful search options (i.e., structure, sub-structure, solvent, literature reference, and more) in spectral libraries for fast and efficient compound identification
    Reporting
    • Print reports directly from the database record
    • Create custom report templates
    • Export to Microsoft Office documents (Word, PowerPoint), and Adobe PDF files
