Rate constants for the reaction, O+H2O→OH+OH, have been measured by the Flash Photolysis-Shock Tube (FP-ST) technique over the temperature range, 1500–2400 K. This technique combines shock heating with flash photolysis in the reflected shock wave regime, and the transient species, O-atoms...
The rate constants are in good agreement with the previous flow drift tube measurements at the same translational temperatures. Any dependence of the rate constant on internal energy is therefore small.关键词: Reaction rate constants Flow rate measurement Flowing afterglow Transfer reactions Charge ...

It has been suggested that the models underestimated the loss of CH3 due to poor knowledge of the rate constant k of the CH3 + CH3 self-reaction at the low temperatures and pressures of these atmospheres. Motivated by this suggestion, we undertook a combined experimental and photochemical mo...
The rate constant for the reaction of CH(a4Σ) with NO is (4.2 ± 0.7) × 10-11 cm3 molecule-1 s-1. Carbon monoxide interacts more slowly with CH(a4Σ), with a pressure independent rate constant of (8 ± 2) × 10-13 cm3 molecule-1 s-1. Only upper limits could be set for ...

Rate constants have been measured for the reaction of Ar+(2P3/2) with N2as a function of N2vibrational temperature for a rotational and translational temperature of 300 K. The rate constants increase from a value of 1.2×10−11cm3s−1at a N2vibrational temperature of 300 K to 2.0×10...
The rate constant for the reaction of Cl with CHCl 3 was measured relative to the Cl reaction with CH 4 and CH 3 Cl using long path FTIR. The measured rate constant at 298 K and 1 atm total pressure was (1.21 ± 0.13) × 10 13 cm 3 molecule 1 s 1 (2σ) about 60% larger ...
