All NMR vs Ahoc

App to predict ¹³C and ¹H NMR spectra: draw a structure to see its spectra. The accuracy (Mean Average Error) of the algorithm is about 1.5 ppm for ¹³C and 0.21 ppm for ¹H (RMSE = 2.8 and 0.31 ppm correspondingly). - Instantly re-calculate spectra while changing structure; - Predicted spectra stored in iCloud and synchronised among all iOS devices and Mac version; - Email PDF report; - Zoom in spectrum; - Zoom in structure (important for iPhone users); - Option to display chemical shift values on structure; - Simple clean interface. The prediction algorithm is a combination of neural network and spheric codes based algorithms.
