A software to visualize, analyze and process 1D and 2D NMR spectra directly from the browser that you can test for free. Designed for analytical and organic chemists as well as for teaching.
Modgraph – NMRPredict. NMR Predict is used to predict 1D (1H, 13C, 15N, 19F, 31P, 17O, 29Si) NMR spectrum for small molecules. The current license allows two simultaneous users to access the NMRPredict database. An online NMRPredict Guide (pdf) is available to assist new users.
This demo will simulate 1 H and 13 C NMR spectra, as well as the mass spectrum parent peak (isotopic distribution), of the molecule you draw in the sketcher. Click the Simulate Spectra button to simulate the spectra when you finish drawing your molecule.
The 13 C NMR predictor is a machine learning-based predictor for small molecules. The predictor accepts the molecular structure and returns the predicted 13 C chemical shift values in ppm in D2O, CDCL3, DMSO or CD3OD solvent.
Test of Equivalence: 1.Do a mental substitution of the nuclei you are testing with an arbitrary label (your book uses X) 2.Ask what is the relationship of the compounds with the arbitrary label 3.If the labeled compounds are identical (or enantiomers), then the original nuclei are chemically equivalent and will normally
