Measurement of OH reactivity by laser flash photolysis coupled with laser-induced fluorescence spectroscopy [PDF]

Atmospheric Measurement Techniques, 2016
OH reactivity (k′OH) is the total pseudo-first-order loss rate coefficient describing the removal of OH radicals to all sinks in the atmosphere, and is the inverse of the chemical lifetime of OH.
