WebAires-de-Sousa, M. Hemmer, J. Gasteiger, “Prediction of 1H NMR Chemical Shifts Using Neural Networks”, Analytical Chemistry, 2002, 74(1), 80-90 most of the proton descriptors are explained. In that work they were used for the prediction of 1H NMR chemical shifts by counterpropagation neural networks.
WebSimulate 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.
WebTrain the predictor. using AI to get even better predictions results. Mnova NMR Predict calculates accurate and precise NMR chemical shifts using a novel procedure that combines several prediction engines in a constructive way. Several machine learning methods are combined with increments and HOSE-code algorithms. Features.

WebThis 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.
WebPredicting the NMR spectrum for a chemical compound can play an important role in structure validation and elucidation. The NMR Predictor is a standalone tool that can predict both 1 H and 13 C NMR spectra of organic compounds. NMR Predictor QuickHelp. The picture below gives a quick overview on the capabilities of Chemaxon's NMR Predictor.
WebMnova NMR Predict calculates accurate and precise NMR chemical shifts using a novel procedure that combines several prediction engines in a constructive way. This method is called Ensemble NMR Prediction and uses several Machine Learning methods in combination with the well-knonwn Increments and HOSE-code algorithms developed by …
WebNMR Predictor. This page illustrates how JSME (the JavaScript Molecular Editor) can be used along with JSpecView to obtain a simulated NMR spectrum for a chosen compound. These two views along with the 3D JSmol model, can be used in any combination. JSmol on this page calls servers in Frederick, Maryland ( NIH resolver, for name-to-structure ...
