Figure 2.14 Transfer from state 9 to state 8 when following adiabatically the resonance issued from 9 around the exceptional point where the resonance energies from 8 to 9 are merging. The paths are as follows thin solid curve, the two-channel model thin dashed curve, four channels, with inclusion of the two lower channels of Figure 2.8 thick dashed curve, four channels, with inclusion of the two higher channels of Figure 2.8 thick solid curve, six channels, with inclusion of all channels of Figure 2.8.

Recent reviews of the excited noble gas atoms have emphasized individual reaction channels chemiionization by Fontyn, Muschlitz, " - and Niehaus, energy transfer and dissociative excitation by Stedman and Setser ° and recombination reactions by Golde and Thrush this approach is very much representative of previous research in this field. Very recently, however, the discovery of gas-phase lasers based on at least four of the available channels, (3), (S), "- (10), " ... 

The primary initial thermal process is a four-center molecular elimination of water, although the C—C and C—O bond fissions cannot be entirely neglected at high temperatures. With only three heavy atoms in ethanol, pressure effects on the rate constants are significant under many conditions. In 2004, Li et al. provided parameterized pressure-dependent rate constants for the first two channels, and Tsang reported a detailed analysis of energy transfer effects and provided assessments for all three of the above channels. Updated combustion models validated for various conditions are given by Li et al., Saxena and Williams, Haas et al., Leplat et al., Lee et al., and Metcalf... 

Instead, the decrease in voltage is due to four different contributions on the anode side Gibbs free energy of the fuels in the mixture, Nernst effect, charge transfer on the anode electrode, mass transport on the anode channel and on the electrode.
