13C NMR is an app that allows users to draw a chemical structure and instantly view its corresponding 13C NMR spectrum. The algorithm is accurate to within 2.0 parts per million (RMSD=3.5 ppm). Features include the ability to draw a structure, recalculate the spectrum while changing the structure, exchange data with other devices via iCloud, print reports, zoom in on the spectrum, and display chemical shift values on the structure.
