The reaction of HO2 radicals with NO is a critical part of the atmospheric ozone cycle, but the plethora of involved species makes it hard to fully decipher. Here, quantitative and simultaneous determination of multiple reaction species, including HO2 and OH radicals, is achieved by means of high-resolution time-resolved dual-comb spectroscopy.
