Fig. 1

The open symbols represent time-resolved signals of a CH2OO absorption line at 1285.611 cm‒1 recorded with a time resolution of 5 μs. The solid lines represent fitting curves. Each temporal profile was fitted with a single-exponential function to obtain the decay rate coefficient (kobs). The data correspond to experiment 1–6 listed in Supplementary Table 1 with total pressure PT = 13.3 Torr, temperature 296 K, and [CH2OO]0 ≈ 7.4 × 1012 molecule cm−3. The derived kobs as a function of [HCHO]0 are shown in Supplementary Fig. 4.
