App to predict 13C NMR spectrum: draw a structure to see its spectrum. The accuracy of the algorithm is about 1.9 ppm (RMSD=3.4 ppm).

- Instantly re-calculate spectrum while changing structure;
- Predicted spectra stored in iCloud and synchronised among all iOS devices and Mac version (itunes.apple.com/app/13c-nmr/id660721455)
- Email PDF report;
- Zoom in spectrum;
- Zoom in structure (important for iPhone users);
- Option to display chemical shift values on structure;
- Simple clean interface.
