Popis:	Seven different tetraphenylpyridinium esters were chosen as model compounds for studying gas phase pyrolysis reactions by Fourier Transform Ion Cyclotron Resonance Mass Spectrometry (FTICR/MS) Collisionally Activated Dissociation (CAD) using cation tagging. In this technique a stable positive charge (tetraphenyl pyridinium) is introduced to one end of the system so the reaction that occurs at the other end can be monitored easily using mass spectrometry. Threshold fragmentation energies and rate constants were calculated for all seven starting materials and a comparison of their observed relative fragmentation rates was made.
