開催内容

Probing molecular anions by charge transfer experiments: key studies on biomolecules

Over the last 10 years we have been dedicated to comprehensive studies on negative ion formation in collisions of neutral fast potassium atoms with neutral biomolecular targets. Negative ions formed by charge transfer have been time-of-flight (TOF) mass analysed. The rich fragmentation pattern as well as the collision induced dissociation dynamics have allowed to probe the role of the unimolecular decomposition processes. As so, we have investigating collisional excitation and dissociation processes; the role of site- and bond-selectivity in pyrimidines and purines; the role of the collision complex and how it influences new fragmentation pathways; and competitive and even concerted fragmentation mechanisms. In this seminar we will present the most recent experimental data on negative ion formation in electron transfer experiments from collisions of neutral potassium atoms with key biomolecular targets, highlighting particular selected achievements.
