OPIG-DC-resolved proton transfer reactions of cytochrome c ions to 1,4-butanediamine (Bda) were examined in the gas phase. Absolute reaction rate constants for proton transfer were determined from intensities of precursor and product ions in the mass spectra. With changes of direct current (DC) voltage to put octapole ion guide (OPIG) of the collision cell, remarkable change was observed for distribution of product ions and reaction rate constants. The results indicate that conformation changes on ions at OPIG-DC voltage range, which relate with complex formation. An issue that is attracting considerable attention is their conformations might resemble structural evolution that originated from internal energy in the gas phase.
