Lifetimes and Quenching Rate Constants Relevant to Remote Sensing of Hydroxyl Radicals with 308nm Excitation (XeCℓ)

To date, frequency doubled tunable dye lasers operating near 282nm have been used as the excitation source in the majority of determinations of atmospheric hydroxyl radical concentrations. However, excitation at 308nm using a tunable xenon-chloride excimer laser has significant advantages over present methods. Some of these advantages are summarized below.
