Title:   Reactions of C-2(a (3)Pi(u)) with selected saturated alkanes: A temperature dependence study
Journal:   J. Chem. Phys.
Volume:   132
Year:   2010
Reference type:   Journal article
Squib:   2010HU/ZHA164312

Reaction:   C2(a3PIu) + iso-C4H10 → Products
Reaction order:   2
Temperature:   298 - 673 K
Pressure:  1.27E-2 bar
Rate expression:   7.86x10-13 [±2.73x10-13 cm3/molecule s] (T/298 K)(2.70±0.05) e8495 [±185 J/mole]/RT
Category:  Experiment
Data type:   Absolute value measured directly
Pressure dependence:   None reported
Experimental procedure:   Static or low flow - Data taken vs time
Excitation technique:   Flash photolysis (laser or conventional)
Time resolution:   In real time
Analytical technique:   Laser induced fluorescence
Comments:   The uncertainties are those of the fit. Apparently, the modified Arrhenius expressions given in the article for the reactions of isobutane and n-hexane are mixed up. The expressions quoted here are assigned to individual reactions based on the rate constant values in Table I and Figures 6 and 7 of the article
