Journal ArticleDOI
Thermodynamics and Mechanisms of Protonated Diglycine Decomposition: A Computational Study
P. B. Armentrout,A. L. Heaton +1 more
TL;DR: A full computational description of the fragmentation reactions of protonated diglycine (H+GG) is presented, and the mechanism for the combined loss of carbon monoxide and ammonia is explored for the first time.
Journal ArticleDOI
Infrared spectroscopy of divalent zinc and cadmium crown ether systems.
TL;DR: Spectra with the largest and most flexible crown ether, 18c6, indicate that the crown is highly distorted, wrapping in a tight cage-like structure around both dications studied, and these competing influences are reflected in both the spectra and lowest-energy conformations.
Journal ArticleDOI
The appearance energy of CF+3 from CF4: ion/molecule reactions related to the thermochemistry of CF+3
Ellen R. Fisher,P. B. Armentrout +1 more
TL;DR: In this paper, the appearance energy for CF+3 from CF4 was measured and it was shown that there is no flouride transfer equilibrium between CF + 3 and CF4, and that the thresholds for formation of CF+ 3 from reaction of ground state Kr+ (2P32) with CF4 and from collision-induced dissociation of CF +3 by Xe are used to establish AE(CF+3/CF4).
Journal ArticleDOI
Energetics and dynamics in the reaction of Si+ with SiF4. Thermochemistry of SiFx and SiF+x (x=1, 2, 3)
M. E. Weber,P. B. Armentrout +1 more
TL;DR: In this article, the authors measured the absolute reaction cross sections as a function of kinetic energy from thermal to 40 eV, and three endothermic product channels were observed, and the dominant SiF++SiF3 channel is only slightly endothermous, while the SiF+3 +SiF and SiF +2+SiF2 channels have much higher thresholds.
Journal ArticleDOI
Effect of kinetic and electronic energy on the reactions of Ti+ with H2, HD, and D2
J. L. Elkind,P. B. Armentrout +1 more
TL;DR: In this paper, the authors examined the reactions of atomic titanium ions with H2, HD, and D2 using a guided ion beam tandem mass spectrometry and obtained a 0 K bond dissociation energy for TiH+ of 2.31 ± 0.11 eV.
