Journal ArticleDOI
The multiplexed chemical kinetic photoionization mass spectrometer: a new approach to isomer-resolved chemical kinetics.
David L. Osborn,Peng Zou,Howard A. Johnsen,Carl C. Hayden,Craig A. Taatjes,Vadim D. Knyazev,Simon W. North,Darcy S. Peterka,Musahid Ahmed,Stephen R. Leone +9 more
TL;DR: The multiplexed three-dimensional data structure (intensity as a function of molecular mass, reaction time, and photoionization energy) provides insights that might not be available in serial acquisition, as well as additional constraints on data interpretation.
Journal ArticleDOI
Thermochemistry of the R−O2 Bond in Alkyl and Chloroalkyl Peroxy Radicals
Vadim D. Knyazev,Irene R. Slagle +1 more
TL;DR: In this paper, an improved kinetic mechanism was proposed to account for further reactions of the RO2 adduct, and ΔH°298(R + O2 ⇄ RO2) values were obtained from the third-law treatment of the temperature dependencies of the equilibrium constants KP(T) resulting from the reinterpretation of the original kinetic data.
Journal ArticleDOI
Kinetics of the C2H3 + H2 ⇄ H + C2H4 and CH3 + H2 ⇄ H + CH4 Reactions
TL;DR: In this article, the potential energy surface and properties of the transition state for reactions (1, −1) were studied by ab initio methods and used to create a transition state model of the reaction.
Journal ArticleDOI
Weak collision effects in the reaction C2H5 ⇌ C2H4 + H
Y. Feng,Jukka T. Niiranen,Jukka T. Niiranen,Ákos Bencsura,Vadim D. Knyazev,D. Gutman,Wing Tsang +6 more
TL;DR: In this paper, a master equation analysis of C[l angle][Delta]E[r angle][sub down] for the exponential down energyloss probability was obtained for each experiment performed and the microcanonical rate constants needed to solve the master equation were obtained from a transition state model for the reaction which is described.
Journal ArticleDOI
Experimental and Theoretical Study of the C2H3 ⇄ H + C2H2 Reaction. Tunneling and the Shape of Falloff Curves
Vadim D. Knyazev,Irene R. Slagle +1 more
TL;DR: In this paper, the authors studied the kinetics of the unimolecular decomposition of the C2H3 radical in a tubular flow reactor coupled with a photoionization mass spectrometer.
