✦ Synopsis

The rate coefficient of the reaction CHzOH + 02 -HO2 + CH20. has been measured at 300 K by the LMR flow-tube method, and found to have the unexpectedly large value k = (2J) x 1O-'2 cm3 molecule-' s-I_ This reaction. preceded by fiomenzafion, may be an important route for the oxidation of CHJO m the upper atmosphere. One of the surprises encountered durmg measurements of the laser magnetic resonance (LMR) spectrum of CH,O [l] was that the source reaction, F + CH30H + CH30 + HF, also generated intense LMR spectra of HO,. These spectra could be mtenslfied further by addmg oxygen to the gas-flow system, and subsequent efforts showed that they could be ehmmated by purifying the inlet gases and by making the flow system ngorously leak-tight.

## Abstract The reaction of hydroxyl [OH] radicals with formaldehyde [CH~2~O] was studied at temperatures ranging from 934 K to 1670 K behind reflected shock waves at an average total pressure of 1.6 atm. OH radicals were produced by shock‐heating tert‐butyl hydroperoxide [(CH~3~)~3~COOH], while
