Abstract: The unimolecular dissociation reactions of doubly charged ions were reported,which resulted from a tandem mass spectrometer and a reversed geometry double focusing mass spectrometer by electron impact.Mass analyzed ion kinetic energy spectrometry(MIKES) was used to obtain the kinetic energy releases in charge separation reactions of doubly charged ions.The intercharge distances between the two charges at transition states can be calculated from the kinetic energy releases.Transition structures of unimolecular dissociation reactions were infered from MIKES and MS/MS.

Key words: Double charged ions, Mass analyzed ion kinetic energy spectrometry(MIKES), Tandem mass spectrometry(MS/MS), 4,4'-Diaminodiphenyl-ether, 4.4'-Diaminodiphenylsulfide
