Abstract

A number of elementary reactions of hydroxyl (OH) and methyl (CH₃) radicals were studied in a shock tube by transient UV absorption using a novel multi-pass absorption cell for sensitive monitoring of transient species. The multi-pass cell consisted of two dielectric mirrors comprising a stable cavity and is used with traditional light sources. Single-shot kinetics with the initial concentration of OH radicals ≥ 5 × 10¹² molecule/cc were recorded. The majority of the measurements were performed with the [OH]₀ = (1 - 2) × l0¹³ molecule/cc. A number of radical precursors were tested and (partially) characterized. For OH, pyrolysis of C₂H₅I/NO₂ mixtures or pyrolysis of HNO₃ were used. To produce OH and CH₃, pyrolysis of (CH₃)₃COOH/(CH₃)₃ COO(CH₃)₃, or pyrolysis of CH₃OH, were used. The kinetic results and the directions of the further development of the technique were discussed. Original is an abstract.
