โฆ Synopsis
Reactions of the hydroxyl radical with several linear hydrocarbon species occurring in combustion chemistry have been considered at temperatures near I100 K and 1 atmosphere in shock tube experiments The OH density was monitored using 310 nm UV absorption of the A 'E+ -X 'n transition Rate coefficients for the reaction of OH with ethane (8.37 X c m ' molecule-' s -' , 970 K ) , hexane (2.18 X lo-", 962 K ) , heptane (3.34 X lo-", I186 K ) , octane (4.42 X lo-". 1078 K]. nonane (4.55 X lo-". 1097 K). and decane (5.64 X lo-". I 109 K) have been determined. These values are compared with previous experimental results and transition state theory calculations 0 1996 John Wiley G Sons. tnc

## Abstract The reaction between methyl and hydroxyl radicals has been studied in reflected shock wave experiments using narrowโlinewidth OH laser absorption. OH radicals were generated by the rapid thermal decomposition of tertโbutyl hydroperoxide. Two different species were used as CH~3~ radical
