Abstract: Formic acid, one of the most abundant acids in the Earth's atmosphere, plays an important role in atmospheric acidity. Here, we report the direct observation of formic acid generated by the reaction of the simplest Criegee intermediate (CH₂OO) with formaldehyde (HCHO). By employing mid-infrared comb lasers and synchronized two-color time-resolved dual-comb spectroscopy, we investigated the kinetics of the reaction CH₂OO + HCHO as well as the yields of the reaction products HCOOH + HCHO and CO + H₂O + HCHO. The potential implications of the reaction CH₂OO + HCHO in the atmospheric chemistry are also discussed in this work.
