Reaction of hydroxyl radicals with C4H5N (pyrrole): temperature and pressure dependent rate coefficients.
Although the pressure and temperature dependent rate coefficient is adequately represented by a falloff parametrization, calculations of the potential energy surface indicate a complex reaction system with multiple reaction paths in the falloff regime. Expand
Absorption cross section and photolysis of OIO.
Pulsed laser photolysis combined with transient absorption spectroscopy and resonance fluorescence was used to examine the photolysis of OIO at a number of wavelengths corresponding to absorptionExpand
Laser induced fluorescence studies of iodine oxide chemistry. Part II. The reactions of IO with CH3O2, CF3O2 and O3.
In the course of this work, the product yield of IO from the reaction of CH(3)O(2) with I was determined to be close to zero, whereas CH (3)OOI was formed efficiently at 70 Torr N(2). Expand
LIF studies of iodine oxide chemistry. Part 3. Reactions IO + NO3 --> OIO + NO2, I + NO3 --> IO + NO2, and CH2I + O2 --> (products): implications for the chemistry of the marine atmosphere at night.
Box model calculations showed that efficient OIO formation in was necessary to explain field observations of large OIO/IO ratios, and a IO product yield close to unity determined. Expand
Absorption cross-section of IO at 427.2 nm and 298 K
Abstract The absorption cross-section of the IO radical was determined at a wavelength of 427.2 nm and at a resolution of ≈0.08 nm at room temperature (298 ± 2 K) using the technique of laserExpand
Atmospheric chemistry, sources and sinks of carbon suboxide, C 3 O 2
Abstract. Carbon suboxide, O  =  C  =  C  =  C  =  O, has been detected in ambient air samples and has the potential to be a noxious pollutant and oxidant precursor; however, its lifetime and fate inExpand
A laser photolysis-resonance fluorescence study of the reactions: I + O3 --> IO + O2, O + I2 --> IO + I, and I + NO2 + M --> INO2 + M at 298 K.
Rate coefficients for the termolecular reaction (R7) were found to be in the falloff region between 3rd and 2nd order behaviour and, when combined with other datasets obtained at higher and lower pressures, were adequately described by a simplified Troe function. Expand
Quantum chemical and kinetics study of the thermal gas phase decomposition of 2-chloropropene.
An analysis of the branching ratio between the two channels as a function of pressure and temperature, based on these results and on computed specific rate coefficients, show that the propyne forming channel is predominant. Expand
Kinetics of the reactions of FC(O)O2 radicals with F atoms and F2
Abstract The kinetics and the mechanism of the 248 nm laser flash photolysis of oxalyl fluoride, (FCO) 2 , in the presence of O 2 , F 2 and the bath gases He and SF 6 has been studied at 295 K. TheExpand
Ab initio and density functional theory study of the enthalpies of formation of F2SOx and FClSOx (x=1, 2)
Abstract Enthalpies of formation of F 2 SO, F 2 SO 2 , FClSO and FClSO 2 molecules have been determined using ab initio molecular orbital theory and density functional theory (DFT) calculations.Expand
