On the mechanism of the CO self-exchange reaction

Abstract

Spin valve effect in self-exchange biased ferromagnetic metal/semiconductor bilayers Appl.Equilibrium constants of hydrogen-deuterium-tritium selfexchange reactions in water vapor as studied with a pulsed molecularbeam quadrupole mass filterThe gas phase exchange reaction with stoichiometry 13e 16 0 + 12e 18~l3e 18 0 + 12e 16 0 has been studied using a mercury photosensitization technique. The mechanism of the photosensitized exchange reaction is complex and almost certainly involves electronically excited eO(a 3 n). No evidence for a simple bimolecular exchange mechanism involving ground electronic state, vibrationally excited CO was found, although such a mechanism is not conclusively ruled out by the photosensitization experiments for vibrational levels higher than 9. Since such a mechanism has previously been proposed based on shock tube studies, a computer simulation of the shock tube exchange reaction was undertaken. One set of shock tube experiments can be reinterpreted quite well in terms of an atomic chain mechanism initiated by traces of O 2 impurity. The mechanism of the second set remains a mystery.PAeS numbers:
