Monitoring intramolecular proton transfer with ion mobility-mass spectrometry and insourceion activation

Here, we show how intramolecular proton transfer can be induced and monitored with the exampleof polycyclic aromatic amines using in-source ion-activation and ion mobility-mass spectrometry. Experimentand DFT calculations reveal that the protonation rate of C-atoms in aromatic rings is controlled by the energybarrier of intramolecular NH۳+ → C proton transfer
