On reaction rate constants and rate kernels

Chemical Physics Letters, 1978
Abstract A simple model for a reversible isomerization reaction A ⇋ B is used to show how rate constants and their time-dependent generalizations can be related to microscopic reactive steps and nonreactive internal dynamics (e.g., vibrational relaxation).

Rate constant for the reaction of CH3O2 with NO

Chemical Physics Letters, 1994
Abstract The CH3O2 radical was generated by pulsed laser photolysis and was detected directly by photoionization mass spectrometry. The radical was photoionized by the Ar resonance lines (11.62 and 11.83 eV) and detected as the parent ion, CH3O+2.

Rate constants for aminyl radical reactions

Tetrahedron Letters, 1993
Abstract Rate constants for cyclization of the N -methyl-5,5-diphenyl-4-pentenaminyl radical ( 4 ) and for reaction of this radical with t -BuSH were determined by direct methods.

Rate constant of the reaction of OH with HO2NO2

Chemical Physics Letters, 1981
Abstract A rate constant ratio of 0.268 has been determined for the reactions of OH radicals with peroxynitric acid and propene at 295 K and a total pressure of 1 Torr (M  N 2 ) by application of FTIR spectroscopy and a relative rate method in a 420 xxx reaction chamber.

Rate Constant for the Reaction of O− with Oxygen

Nature, 1965
WE have measured the rate constant for the reaction O− + O2 → O3− by irradiating a solution of aerated 10−1 N potassium hydroxide with a short pulse of fast electrons and observing directly the growth of the transient species O3− which has an absorption maximum at 4300 A (refs. 1 and 2).
