This book was released on 1990 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ions trapped in a Fourier Transform Ion Cyclotron Resonance (FTICR) mass spectrometer exhibited enhanced Infrared Multiple Photon Dissociation (IRMPD) when irradiated sequentially by two carbon dioxide lasers using a novel IRMPD probe/pump photodissociation scheme. A low power pulsed (probe) laser tuned to a resonant infrared absorption band promoted trapped ions to vibrationally excited states, but had insufficient energy to cause photodissociation. Subsequent irradiation of the excited ions with a fixed-frequency, nonresonant, continuous wave (pump) laser induced photofragmentation. Photodissociation spectra were obtained by varying the wavelength of the probe laser. A novel White-type cell which dramatically enhances the effect of the probe laser has been designed and constructed for use with these experiments.

Book Synopsis Photodissociation of Gaseous Ions Formed by Laser Desorption by : Clifford H. Watson
Download or read book Photodissociation of Gaseous Ions Formed by Laser Desorption written by Clifford H. Watson and published by . This book was released on 1986 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: Both pulsed and gated continuous wave carbon dioxide lasers have been employed to desorb ions and then to photodissociate them in a Fourier transform ion cyclotron resonance mass spectrometer. Pulsed CO2 laser irradation was most successful in laser desorption experiments, while a gated continuous wave laser was used for a majority of the successful infrared multiphoton dissociation studies. Fragmentation of ions with m/z values in the range 400-1300 was induced by infrared multiphoton dissocation. Such photodissociation was successfully coupled with laser desorption for a number of different classes of compounds. Either two sequential pulses from a pulsed carbon dioxide laser (one for desorption and one for dissociation) or one desorption pulse followed by gated continuous wave irradation to bring about dissociation were ultilized. Keywords: Carbon Dioxide Lasers; Fourier Transform; Ion Cyclotron Resonance; Mass Spectrometry; Infrared Multiphoton Dissociation; Laser Desorption.

Book Synopsis Mass-selected Infrared Multiple-photon Dissociation as a Structural Probe of Gaseous Ion-molecule Complexes by : Richard Alexander Marta
Download or read book Mass-selected Infrared Multiple-photon Dissociation as a Structural Probe of Gaseous Ion-molecule Complexes written by Richard Alexander Marta and published by . This book was released on 2009 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mass-selected infrared multiple photon spectroscopy (IRMPD), Fourier transform ion cyclotron resonance (FT-ICR) kinetic experiments, RRKM and electronic structure calculations have been performed in order to propose a complex mechanism involving the formation of the proton-bound dimer of water (H5O2) from 1,1,3,3-tetrafluorodimethyl ether. It has been found that the reaction is facilitated by a series of sequential exothermic bimolecular ion-molecule reactions. Evidence for the dominant mechanistic pathway involving the reaction of CF2H-O=CHF2, an ion of m/z 99, with water is presented. The primary channel occurs via nucleophilic attack of water on the ion of m/z 99 (CF2H-O=CHF), to lose formyl fluoride and yield protonated difluoromethanol (m/z 69). Association of a second water molecule with protonated difluoromethanol generates a reactive intermediate which decomposes via a 1,4-elimination to release hydrogen fluoride and yield the proton-bound dimer of water and formyl fluoride (m/z 67). The 1,4-elimination of hydrogen fluoride is found to be strongly supported by the results of both RRKM theory and electronic structure calculations. Lastly, the elimination of formyl fluoride occurs by the association of a third water molecule to produce H5O2 (m/z 37). The most probable isomeric forms of the ions with m/z 99 and 69 were found using IRMPD spectroscopy and electronic structure theory calculations. Thermochemical information for reactant, transition and product species was obtained using MP2/aug-cc-pVQZ//MP2(full)/6-31G(d) level of theory.

Book Synopsis Nucleic Acids in the Gas Phase by : Valérie Gabelica
Download or read book Nucleic Acids in the Gas Phase written by Valérie Gabelica and published by Springer. This book was released on 2014-07-28 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives physical chemists a broader view of potential biological applications of their techniques for the study of nucleic acids in the gas phase. It provides organic chemists, biophysicists, and pharmacologists with an introduction to new techniques they can use to find the answers to yet unsolved questions. Laboratory sciences have bloomed with a variety of techniques to decipher the properties of the molecules of life. This volume introduces techniques used to investigate the properties of nucleic acids in the absence of solvent. It highlights the specificities pertaining to the studies of nucleic acids, although some of the techniques can similarly be applied to the study of other biomolecules, like proteins. The first part of the book introduces the techniques, from the transfer of nucleic acids to the gas-phase, to their detailed physico-chemical investigation. Each chapter is devoted to a specific molecular property, and illustrates how various approaches (experimental and theoretical) can be combined for the interpretation. The second part of the book is devoted to applying the gas-phase approaches to solve specific questions related to the biophysics, biochemistry or pharmacology of nucleic acids.
