## Abstract Using the mobile proton model as a framework, the influence of charge distribution on the discrepant fragmentation of peptides FMRF, FM(O)RF and FM(O~2~)RF (with united peptide sequence) was explored by mass spectrometry experiments and quantum chemical calculations. With the added O at
