Simulate and predict NMR spectra directly from your webbrowser using standard HTML5. You can also simulate 13C, 1H as well as 2D spectra like COSY, HSQC, HMBC. Second order effect like AB, ABX, AA'XX' can be simulated as well.
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. Add the structure of your natural product by pasting a SMILES or InChI string into the MarvinJS structure drawing applet ...

30 sty 2023 · The NMR spectra on this page have been produced from graphs taken from the Spectral Data Base System for Organic Compounds at the National Institute of Materials and Chemical Research in Japan. Remember that each peak identifies a carbon atom in a different environment within the molecule.
13C Carbon NMR. How is it different from 1H NMR and why there is no signal splitting? What is the ppm range and how to determine the number of signals.
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.
