About 1H NMR

App to predict 1H NMR spectrum: draw a structure to see its spectrum. The accuracy of the algorithm is about 0.21 ppm (RMSD=0.31 ppm) obtained on a large independent dataset.

- Instantly re-calculate the spectrum while changing the structure;
- 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 derived by:
K. A. Blinov, E. D. Smurnyy, T. S. Churanova, M. E. Elyashberg, A. J. Williams, Chemom. Intell. Lab. Syst. 2009, 97, 91
