Carbon dioxide (CO₂), methanol (CH₃OH), ethanol (CH₃CH₂OH), and formic acid (HCOOH) have been formed in collisions of a superthermal, 9 eV beam of O(³ P) atoms with CH₄molecules, with an over coat of CO molecules, adsorbed on a gold surface at 4.8 K. The products are detected using temperature programmed-desorption and quadrupole mass spectrometry. Identification of the species is carried out through use of the Metropolis random walk algorithm as constrained by the fractionation patterns of the detected species. Relative formation yields are reported and reaction sequences are given to account for possible formation routes.
