chlorine chemistry and hydrocarbon chemistry has taken on new importance in the last few years with the realization that chlorine chemistry may play a more important role in the marine troposphere than previously thought. Measurements of hydrocarbons in the Arctic troposphere in springtime have prov

β¦ Synopsis
A combined EPR-LMR spectrometer with a fast-flow system has been used to investigate the kinetics and mechanisms of NF2 reactions with 0 and N atoms a t 298 K. The overall rate constants of these reactions are: ko = (2.8 f 0.4) X lo-" cm3/s and k~ = (5.7 f 0.8) X lo-" cm3/s. The stoichiometry of the reactions with respect to 0, N, NF2, F, and NO has been determined. The statistical theory of bimolecular reactions has been used for interpretation of the results obtained.

## Abstract The kinetics and mechanism of the reaction of chlorine atoms with __n__βbutanal and __n__βpentanal have been investigated in a 142βL reaction cell coupled to a Fourier transform infrared (FTIR) spectrometer at 298 Β± 2 K and at 800 Β± 3 Torr. The rate coefficients for Cl + __n__βbutanal a
Rate constants for the reactions of N and 0 with CF and CF2 radicals have been measured in a gas-flow system with photoionization mass spectrometry detection. CF( % 211,,2,,,2) and CF,(% 'A, ) radicals were produced in a radiofrequency discbarge of CFBr3 and CF2Br?, respectively. Atomic reactants we
The kinetics of the reaction of 0 atoms with NO2 was investigated in the temperature range 199-357 K. The value of the rate constant can be expressed by k, = (5.21 kO.50) x lo-'\* exp [(202\*27)lT] cm3 s-' (3~ error). At temperatures below 230 K, the formation of equilibrium concentrations of N204 a
The kinetics and mechanism of the reaction Cl Ο© HO 2 : products (1) have been studied in the temperature range 230-360 K and at total pressure of 1 Torr of helium using the discharge-flow mass spectrometric method. The following Arrhenius expression for the total rate constant was obtained either fr
