Squib:   2000PAP/ARE79-84

Reaction:   Pentanal + ·OH → Products
Reaction order:   2
Reference reaction:   C2H5COCH3 + ·OH → Products
Temperature:   296 K
Pressure:  0.99 bar
Rate expression:   2.99x10-11 [±1.9x10-12 cm3/molecule s]
Bath gas:   Air
Category:  Experiment
Data type:   Relative value normalized by a reference value
Pressure dependence:   None reported
Experimental procedure:   Static or low flow - Data taken vs time
Excitation technique:   Direct photolysis
Time resolution:   In real time
Analytical technique:   Gas chromatography
Comments:   Experiments were carried out in a 6500 Liter all Teflon chamber at 296 ?2 K.
OH was generated by the photolysis of CH3ONO at wavelengths above 300 nm in the presence of NO.

The reference reaction was OH + methyl vinyl ketone with accepted k= 2.06E-11 cm3molecule-1s-1.

Indicated errors are two standard deviations and do not include uncertainties in the rate constant of the reference reaction (estimated to be ?10 - 15 %).
