✦ Synopsis

Abstract

HCO radical at a concentration of about 10^14^ cm^−3^ is produced by monochromatic laser photolysis of H~2~CO 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 HCO + O~2~ and HCO + NO are found to be 4.0 ± 0.8 × 10^−12^ and 1.45 ± 0.2 × 10^−11^ cm^3^ molecule^−1^ sec^−1^.
