Available in PDF, EPUB and Kindle. Book excerpt: By analyzing the photoelectron energies in several systems, it has been demonstrated that multiphoton ionization (MPI) can selectively produce molecular ions predominantly in a single vibrational level by the proper choice of the laser wavelength employed. Thus MPI provides a powerful new technique for producing high densities of internally state-selected reagent ion for chemical reaction dynamics studies. This approach is being taken for studying the ion-molecule reactions of NH3(+) (v) which has been prepared with v = 0-9 vibrational quanta in the nu sub 2 umbrella-bending mode.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantum state resolved pulsed field ionization-photoion (PFI-PI) spectra of several small molecules have been obtained, and a few state-selected and kinetic energy selected ion molecule reactions have been studied in detail in this dissertation. Tunable vacuum ultraviolet (VUV) laser is employed, along with a PFI-PI double-quadrupole double-octupole (DQDO) mass spectrometer to conduct these spectroscopic and chemical dynamics studies. Electronic, vibrational, and rotational selected ions are produced by direct photoexcitation with intense, high-resolution VUV laser to high-n Rydberg states, then field ionized by external pulsed electric fields. Pulsed electric field sequences, including their intensity and duration, are adjusted for each unique molecular ion studied to achieve ion beam kinetic energy resolution of as good as 0.05 eV in the lab frame (E[subscript lab]). Kinetic energy dependent integral cross section measurements are measured in the center-of-mass kinetic energy (E[subscript CM]) range of 0.05 – 10.0 eV. Octupole ion guides are used to transmit reactant and product ions from the source to the mass spectrometer with high transmission efficiency. Quadrupole mass spectrometer is used to selectively transmit ions with specific mass to charge ratio. It is demonstrated a wide range of molecular species can be studied in the present VUV-PFI-PI-DQDO apparatus. In this dissertation, N2+, CH4+, O2+, H2+, H2O+, as well as a transition metal ion V+ are investigated spectroscopically and kinetically. Some quantum state resolved photoions are produced for the first time (e.g. rotational selected H2+, electronically and vibrational selected O2+, and spin-orbit state selected V+). Ion-molecule reactions involving these molecular ions are studied and quantum state effects on their reactivity are noticed and discussed. These include the vibrational state and kinetic energy dependence of the product channels and cross sections of reaction N2+(X2[sigma][subscript g], v+=0-2) + C2H2, the rotational enhancement and more complicated vibrational effects of reaction H2O+(X2B1, v1+v2+v3+, N+[subscript Ka+Kc+]) +HD, the distinctive charge transfer cross sections of O2+(a4[pi][subscript u], X2[pi][subscript g], v+)+Ar with reactant ions in two different electronic states while close in total internal energy, and the vibrational and rotational enhancement of proton transfer reaction of H2+(X2[sigma][subscript g]+, v+=1-3, N+=0-3)+Ne. For the CH4/CH4+ system, it is also shown that through studying the unimolecular dissociation dynamics by the PFI-PI method, thermochemistry data, e.g. appearance energy (AE) and bond dissociation energy (D0), can be obtained with unprecedented accuracy.

Book excerpt: Unimolecular and Bimolecular Ion—Molecule Reaction Dynamics Cheuk-Yiu Ng, Ames Laboratory, Iowa State University, Iowa, USA Tomas Baer, University of North Carolina, NC, USA Ivan Powis, University of Nottingham, UK Recent advances in both experimental techniques and theoretical methodologies have meant that increasingly sophisticated studies concerning the formation, structures, energetics, and reaction dynamics of state- or energy-selected molecular ions can now be performed. In order to better serve the ion chemistry and physics community, each volume of this series will be dedicated to reviewing a specific topic, emphasizing new experimental and theoretical developments in the study of ions. This third volume is devoted to the study of unimolecular and bimolecular ionic processes. Special emphasis is given to studies related to planetary and interstellar ion chemistry and physics, the understanding of which has been a great impetus to the study of ion—molecule reactions. Each of the nine chapters making up this volume is written by a leading researcher in the respective field. This series will help stimulate new research directions and point to future opportunities in the fields of ion chemistry and physics.

Book excerpt: Reactions of state-selected ammonia cation with D2, D2O, and CD4 were studied using a guided-ion beam instrument. The influence of vibrational and collision energy on these reactions was investigated by measuring cross sections for reaction of (NH3)(+) created with varying degrees of excitation in the umbrella bending- and symmetric stretching-modes. A comparison of the product cross sections from (NH3)(+) created in two states of nearly identical internal energies, but different concerted atom motions indicated that none of these reactions is mode-selective. The state-to-state ion-molecule reaction (ND3)(+) + D2O -- (ND4)(+) + OD was investigated. Rotational distributions were determined for the fine-structure states of the OD product for the reaction of vibrationally excited reactant ion. We also studied the proton transfer channel for the reaction of (HBr)(+) with HBr. We developed two approaches exploiting optical laser sources to diagnose specific chemical species present in hostile environments In particular, cavity ring-down spectroscopy and two-photon light induced fluorescence were deployed to detect potential reactants present in a hot-filament chemical vapor deposition system used to grow diamond films. Finally, we used quadrupole mass spectrometry to detect the diatomic dications (BaX)(2+) (X=F, Cl, Br, I), (SrCl)(2+), (CaBr)(2+), and (MgBr)(2+).
