The mechanisms of BF, BCI, AIF and AICI reacting with 302 have been investigated by ab initio molecular orbital methods at the PMP4/6-31G \* and G2 levels of theory. The BX + 302 reactions proceed via an XBOO intermediate that can dissociate to give XBO + 30, which can react further to yield BO 2 +
A common approximation used in ab initio molecular orbital calculations assumes that the changes in energy due to use of a larger basis set (as in the inclusion of polarization orbitals) and to allowance for electron correlation are additives. Thus, small basis sets may be used for correlated ab ini
