Available in PDF, EPUB and Kindle. Book excerpt: The dissociation of highly vibrationally excited molecular ions resulting from single infrared photon absorption has been studied. The wavelength dependence of the absorption/dissociation process has been measured, and the photofragments identified. Measurements were also made of the dissociative lifetime following absorption and the photofragment kinetic energy distributions. These measurements show that a strong correlation exists between this single photon dissociation process and the final step of multiphoton dissociation. Based on these results, the dissociation dynamics appear to follow a single statistical mechanism. (Author).
Download or read book Infrared Multiphoton and Collision Induced Dissociation Studies of Some Gaseous Alkylamine Ions written by C. H. Watson and published by . This book was released on 1986 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Collision induced dissociation and infrared multiphoton dissociation of ions formed in di- and triethylamine, di- and tri-n-propylamine, and diisopropylamine were investigated by Fourier transform ion cyclotron resonance mass spectrometry. Molecular ions of all amines except di-n-propylamine produced similar fragment ions when subjected to either dissociation technique. The initial fragmentation involved C(alpha)-C(beta) bond cleavage, loss of an alkyl radical, and formation of an immonium ion. Subsequent fragmentations of the immonium ions produced by both dissociation mechanisms involved McLafferty type rearrangements and loss of alkenes. The molecular ion of di-n-propylamine fragmented by a different mechanism when subjected to infrared irradiation. Protonated molecules of di- and tri-n-propylamine yielded C3H6 and an ammonium ion upon infrared multiphoton dissociation, while protonated molecules of the other amines did not dissociate using this technique. Collision induced dissociation, on the other hand, produced fragmentation for all protonated molecules. Explanation of the different fragmentations observed for the two dissociation techniques is given in terms of a mechanism involving a tight transition state for protonated di- and tri-n-propylamine dissociation. Keywords: Infrared Multiphoton Dissociation; Collision Induced Dissociation; Alkylamines; Fourier Transform Ion Cyclotron Resonance Mass Spectrometry.

Download or read book Spectroscopy and Modeling of Biomolecular Building Blocks written by Jean-Pierre Schermann and published by Elsevier. This book was released on 2007-10-16 with total page 499 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spectroscopy and Modeling of Biomolecular Building Blocks presents an overview of recent advances in the intertwining of the following research fields: photon and electron spectroscopy, quantum chemistry, modelling and mass-spectrometry. The coupling of these disciplines offers a new point of view to the understanding of isolated elementary building blocks of biomolecules and their assemblies. It allows the unambiguous separation between intrinsic properties of biomolecular systems and those induced by the presence of their environment. The first chapters provide background in modelling (I), frequency-resolved spectroscopy using microwave, infrared and UV photons, time-resolved spectroscopy in the femtosecond domain and energy-resolved electron spectroscopy (II) and production of gas-phase neutral and ionic biomolecular species, mass-spectrometry, ion mobility and BIRD techniques (III). Chapter IV is devoted to case studies of gas-phase experimental investigations coupled to quantum or classical calculations. The topics are structural studies of nucleobases and oligonucleotides, peptides and proteins, sugars; neuromolecules; non-covalent complexes; chiral systems, interactions of low-energy electrons with biomolecules in the radiation chemistry context and very large gas-phase biomolecular systems. The fifth chapter concerns the link between gas-phase and liquid-phase. Different treatments of solvation are illustrated through examples pointing out the influence of progressive addition of water molecules upon properties of nucleobases, peptides, sugars and neuromolecules.
