Journal ArticleDOI
On the Enthalpy of Formation of Hydroxyl Radical and Gas-Phase Bond Dissociation Energies of Water and Hydroxyl
Branko Ruscic,Albert F. Wagner,Lawrence B. Harding,Robert L. Asher,David Feller,David A. Dixon,Kirk A. Peterson,Yang Song,Ximei Qian,Cheuk-Yiu Ng,Jianbo Liu,Wenwu Chen,David W. Schwenke +12 more
TL;DR: In this paper, a consensus value of the appearance energy of the O−H bond energy was derived from a mass-selected photoionization measurements, pulsed-field-ionization photoelectron spectroscopy measurements, and photo-electron-photoion coincidence measurements.
Journal ArticleDOI
Evidence for a Lower Enthalpy of Formation of Hydroxyl Radical and a Lower Gas-Phase Bond Dissociation Energy of Water
Branko Ruscic,David Feller,David A. Dixon,Kirk A. Peterson,Lawrence B. Harding,Robert L. Asher,Albert F. Wagner +6 more
TL;DR: In this article, the authors present an independent experimental determination of the appearance energy that confirms the accuracy and enhances the precision of the existing positive ion cycle value for ΔHf0°(OH).
Journal ArticleDOI
Ionization Energy of Methylene Revisited: Improved Values for the Enthalpy of Formation of CH2 and the Bond Dissociation Energy of CH3 via Simultaneous Solution of the Local Thermochemical Network
TL;DR: In this article, the appearance energy of the CH{sub 2}{sup +} fragment from CH-sub 2}CO has been carefully remeasured and fitted by a model curve, producing EA{sub 0}(CH{sub 3}sup +/CH{ sub 2]CO) = 13743 {+-} 0005 eV.
Journal ArticleDOI
A photoionization study of trifluoromethanol, CF3OH, trifluoromethyl hypofluorite, CF3OF, and trifluoromethyl hypochlorite, CF3OCl
Robert L. Asher,Evan H. Appelman,Jeffrey L. Tilson,Maritoni Litorja,Joseph Berkowitz,Branko Ruscic +5 more
TL;DR: In this paper, the appearance potentials of the first two fragments were accurately determined by fitting with appropriate model functions as AP0(CF2OH+/CF3OH)⩽13.08±0.005
