Abstract

The reactions between reactive radicals and other neutral compounds have long been known to be important in atmospheric chemistry and astrochemistry. This work uses pulsed-laser photolysis cavity ringdown spectroscopy and laser-induced fluorescence to measure the rate constants and branching ratios of chemical reactions over a wide range of temperatures and pressures relevant to both polluted atmospheres, and the interstellar medium. This includes studying the OH + NO₂ reaction in the 253 – 333 K range, the reaction of CN with benzene (C₆H₆) and toluene (C₇H₈) down to 16 K, and the OH + CO reaction down to 30 K.
