Title:   High temperature rate constants for H/D plus n-C4H10 and i-C4H10
Journal:   Proc. Combust. Inst.
Volume:   35
Page(s):   171 - 179
Year:   2015
Reference type:   Journal article
Squib:   2015PEU/SIV171-179

Reaction:   iso-C4H10 + D → Products
Reaction order:   2
Temperature:   1063 - 1327 K
Pressure:  0.51 bar
Rate expression:   2.57x10-9 [cm3/molecule s] e-48207 [J/mole]/RT
Category:  Experiment
Data type:   Derived from fitting to a complex mechanism
Pressure dependence:   None reported
Experimental procedure:   Shock tube
Excitation technique:   Thermal
Time resolution:   In real time
Analytical technique:   Vis-UV absorption
Comments:   D-atom profiles were measured behind reflected shock waves using D-atom atomic resonance absorption spectrometry (ARAS). Ab initio based transition state theory kinetics predictions for the isotope effects, kD/kH, are near unity. Therefore, the quoted expression can be usid for the H atom reaction as well.
