App to predict 13C and 1H NMR spectra: draw a structure to see its spectrum. The accuracy of the algorithm is
about 1.9 ppm for 13C and 0.21 ppm for 1H (RMSD=3.4 and 0.31 ppm correspondingly).
The number of heavy atoms in structure to predict for free is restricted to 12 atoms. This restriction can be removed by purchasing additional licenses.
- Draw chemical structure;

- Exchange data with mobile devices via iCloud;
- Print report;
- Zoom in spectrum;
- Option to display chemical shift values on structure;
- Simple clean interface.
