The shock tube data of Ogura [51 on the pyrolysis of CzHz/NO mixtures (1100-1500 K) is shown to be consistent with a simple mechanism whereby radicals are both initiated and terminated by NO (Scheme I). The scheme accounts for the rate of formation of the main product, vinylacetylene (VA), the lesse

Thermochemical analysis of the electron capture process of SFs leads to a rate constant for the reverse process SF; 2 SF6 + e-, k 2 = 1.5 X 1013-31'.4/H s-l, where 0 = 2.303RT, in kcal/mol. The electron affinity of 32 f 3 kcal/mol is deduced from the observed bimolecularity of the capture process do
Laser flash photolysis of C1,/Oz mixtures has been employed in conjunction with Cl( 2P,,2) detection by time-resolved resonance fluorescence spectroscopy to investigate equilibration kinetics for the reactions C1+Oz +O,:ClOO+O, at temperatures of I8 I-200 K and O2 pressures of 15-40 Torr. The third-
The gas-phase reaction CH3SH + IZ has been studied spectrophotometrically over the temperature range of 476-604 K. It was found that the reaction undergoes H abstraction by I at 5575 K, leading to the formation of MeSI and followed by a secondary reaction which leads to the formation of MeSSMe: Tak
Ester exchange reaction kinetics of oxyphosphoranes with several kinds of alcohols, the model compounds for nucleosides, has been investigated. Comparison of the reaction rates of oxyphosphorane (1) with alcohols indicated that the ester exchange rates of diols were much faster than that of monoalco
