Time- and temperature-resolved proton transfer reactions of biomolecular ions, [M + zH]z+, 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 reaction time and reaction temperature, remarkable change was observed for distribution of product ions and reaction rate constants. The results indicate that conformation changes on [M + zH]z+ at lower temperature range, which relate with complex formation. An issue that is attracting considerable attention is their conformations might resemble structural evolution that originated from temperature in the gas phase.
