Abstract: | Vibrational transition probabilities have been calculated by the Schwartz, Slawsky and Herzfeld method [3] for the deactivation of HO2* in collision with H2, O2 and CO2. The relative efficiencies of H2, O2 and CO2 are compared with their third-body efficiencies found experimentally and it is concluded that the transfer of large vibrational quanta from HO2* is unlikely to play an important part in determining the position of the second explosion limit of the H2/O2 reaction. This conclusion is at variance with the explanation put forward by Walsh [1] of the ‘anomalous’ third-body efficiencies of H2O and CO2 in this reaction. |
