13C NMR Predictor
What is the NMR predictor?
The 13C NMR predictor accepts the molecular structure and returns the predicted 13C chemical shift values in ppm using nmrshiftbd2. Add the structure of your natural product by pasting a SMILES or InChI string into the MarvinJS structure drawing applet below. Alternatively, you can use the applet to draw your structure or to upload an '.mol' file. To learn how to draw a structure in MarvinJS, click on MarvinJS Tutorials
