Selective Excision of Biomolecules in Electron Transfer Experiments: Current Developments and Achievements
Paulo Limao-Vieira, Filipe Ferreira da Silva and Gustavo Garcia
Abstract
Here we revisit electron transfer processes yielding negative ion formation in gas-phase collisions of fast neutral potassium atoms (electron donor) and biomolecular target molecules (electron acceptor) in a crossed molecular-beam arrangement. The negative ions formed in the interaction region are time-of-flight (TOF) mass analysed as a function of the collision energy. Selective site and bond excision in the unimolecular decomposition of the transient negative show clear dependence on the collision energy.
