ResumoTwo O-H stretch bands at 3647.5 and 3598.3 cm−1 have been observed for the previously reported “metastable species” formed by HO2-CH2O interactions. These bands are consistent with the presence of an OH and an OOH group and provide support for the earlier tentative identification of hydroperoxy-hydroxy-methane, CH2(OH)OOH, formed via CH2O + HO2 → CH2(OH)OO, CH2(OH)OO + HO2 → CH2(OH)OOH + O2. This compound is relatively stable in the dark at 25°C.
