The only proton chemical shift caclulator available for the iPhone. Quickly calculate proton NMR chemical shifts for any proton. The chemical shift is automatically calculated based on additivity constants. One can calculate either aliphatic, aromatic or olefinic protons based on substituents and their relative position to the proton whose shift is being calculated.
