Title:   Kinetics of Reactions of C2H Radical with Acetylene, O-2, Methylacetylene, and Allene in a Pulsed Laval Nozzle Apparatur at T=103 K
Journal:   Chem. Phys. Lett.
Volume:   344
Page(s):   317 - 324
Year:   2001
Reference type:   Journal article
Squib:   2001VAK/HEA317-324

Reaction:   C2H2 + ·C2H → Products
Reaction order:   2
Temperature:   103 K
Pressure:  8.00E-4 bar
Rate expression:   1.3x10-10 [±3.0x10-11 cm3/molecule s]
Bath gas:   N2
Category:  Experiment
Data type:   Absolute value measured directly
Pressure dependence:   None reported
Experimental procedure:   Laval nozzle
Excitation technique:   Flash photolysis (laser or conventional)
Time resolution:   In real time
Analytical technique:   Chemiluminescence
Comments:   The C2H radicals have been generated by photolysis of C2H2 at 193 nm.The C2H decay profiles in the presence of both reactant and O2 are monitored by detecting the chemiluminescence of electronically excited CH, formed by the tracer reaction of C2H with O2.
