HCO Radical Kinetics: Conjunction of Laser Photolysis and
Intracavity Dye Laser Spectroscopy
Int. J. Chem. Kinet., 1978, 10, 427.
Abstract
HCO radical at a concentration of about 1E+14 cm-3 is produced by monochromatic
laser photolysis of H2CO with a 0.6 mJ frequency-doubled, flashlamp-pumped dye
laser pulse. Intracavity dye laser spectroscopy quantitatively monitors HCO
absorbance near 614 nm as a function of delay time between photolysis and probing
pulses. Rate constants for reactions (168) and (A) are shown below.
