Gas-phase nitronium ion affinities.
Evaluation of nitronium ion-transfer equilibria, L1NO2+ + L2 = L2NO2+ + L1 (where L1 and L2 are ligands 1 and 2, respectively) by Fourier-transform ion cyclotron resonance mass spectrometry and application of the kinetic method, based on the metastable fragmentation of L1(NO2+)L2 nitronium ion-bound dimers led to a scale of relative gas-phase nitronium ion affinities. This scale, calibrated to ...
متن کاملStructural Investigation, Proton and Electron Affinities, Gas Phase Basicities, and Ionization Energies of Captopril
Captopril is one of the most significant angiotensin-converting enzyme inhibitors. In spite of numerous experimental and computational studies on its properties, not enough geometrical and thermodynamic data is available on this compound. So, this study aimed to investigate the structural properties and assignment of possible conformers of captopril in the gas-phase. To this end, 1152 unique tr...
متن کاملSelected examples of gas-phase ion chemistry studies.
Gas-phase ion chemistry is an area in mass spectrometry that has received much research interest since the mid fifties of the last century. Although the focus of mass spectrometric research has shifted the last twenty years largely to life science studies, including proteomics, genomics and metabolomics, there are still several groups in the world active in gas-phase ion chemistry of both posit...

Biography: Fulvio Cacace was born in Rome in 193 1 and received his undergraduate education at the University of Rome, as a student of Prof. G . Giacomello. Then followed postdoctoral experience at Uppsala, Brookhaven National Laboratory, and Kernforschungauslage Julich and teaching appointments at the Universities of Camerino and Viterbo. Since 1971 he has been Professor of General Chemistry a...
متن کاملAlkali metal cation binding affinities of cytosine in the gas phase: revisited.
Binding of metal cations to the nucleobases can influence base pairing, base stacking and nucleobase tautomerism. Gas-phase condensation of dc discharge generated alkali metal cations and thermally vaporized cytosine (DC/FT) has been found to produce kinetically trapped excited tautomeric conformations of the M(+)(cytosine) complexes, which influences the threshold collision-induced dissociatio...
