Ab initio calculations have been used to study the decomposition pathw
ays of monofluoromethanol. Equilibrium geometries and transition state
structures were optimized at the HF/6-31G(d) and MP2/6-31G(d) levels.
Single point energies were obtained at different levels of theory. Th
e most favorable reaction to dissociation is the 1,2-HF elimination wh
ich is consistent with the experimental results.
