Description
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.
- 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/orange-nmr/id680184249);
- 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:
