TL;DR: In this article, a guided ion beam mass spectrometer was used to examine the kinetic energy dependence of the reaction of ground state atomic oxygen ion with molecular nitrogen, and an O+(4S) source which produces less than 0.06% excited states was described.

TL;DR: The IRPD spectrum of Zn(2+)(H(2)O)(8) is most consistent with the calculated spectrum of the five-coordinate MP2(full) ground-state (GS) species and results from larger complexes also point toward a coordination number of five, although contributions from six-coordinated species cannot be ruled out.

TL;DR: In this article, the authors review their work on the kinetic energy dependence of these reactions as studied by using guided ion beam mass spectrometry and provide unprecedented detail in reaction excitation functions over an extremely wide kinetic energy range, allowing an understanding of the reaction thermochemistry, electronic degeneracy, adiabatic versus diabatic potential energy surfaces and spin-orbit coupling.

TL;DR: In this paper, the fundamental character of carbon dioxide activation at metal centers was studied in the gas phase using guided ion beam mass spectrometry, and the reactions of Y+ and YO+ with CO2 and the reverse reactions, YO+, YO2+, and O2Y(CO)+ with CO were investigated.

TL;DR: In this paper, the stability of the salt bridge (SB; zwitterionic) conformer relative to the most stable canonical structure with a single formal charge site (charge solvation; CS) of aliphatic amino acids (e.g., Pro, Na+, K+, Rb+, and Cs+) was investigated using IRMPD spectroscopy utilizing light generated by a free electron laser and computational modeling.
