Original Investigations


The dissociation curve of fluoromethane in hydrofluoric acid was calculated by anab initio SCF MO technique using the minimal STO-3G basis set. The model of the solvent includes eleven HF molecules, simulating the first solvation shell. The position of these molecules was borrowed from a previous semiempirical calculation. A preliminaryab initio study of solvation of CH 3 + and F+ in H2O and HF justifies this assumption.
