Gas phase ion reaction dynamics

点击翻译按钮获取中文摘要

My research focuses on the dynamics of the reactions of gas-phase ions. The work involves studying the mechanisms for ion dissociation and reactivity in mass spectrometry and the energetic and entropic factors that influence this reactivity. We pursue this work experimentally with mass spectrometry and theoretically with statistical rate theory and computational chemistry. We are particularly interested in: the ion chemistry of small polycyclic aromatic hydrocarbons to help elucidate their role in the chemistry of the interstellar medium; the modeling of experimental tandem mass spectrometry data to extract reliable energetics and entropics for the dissociation of non-covalent complexes, be they polymers or peptides; and new methods for dissociating proteins by electron transfer dissociation involving metal anions.
