Hence, there are potentially at least six reaction paths that can be explored in this system. The focus however is to find the relevance of OSAZ to the dimerization reaction and to the other three species, and therefore not all reaction paths were investigated. The results are shown in table 2. Figure shows the formation of H3SiO4 -from OSAZ. Note that the H3SiO4 -species is charge balanced by the immediately neighboring H3O + formed from the freed proton (fig. ) and will be referred to as "dipolar complex II" from hereon. A second configuration where H3O + is more distant (fig. ) but much higher in energy was also found. The energy profiles corresponding to the configurations in figures 4 and 5 are shown in figure .
