摘要：

The heats of formation of the keto and enol forms of the molecular ion of methyl acetate are 577 ± 4kJ mol−1 and 477 ± 4KJ mol−1 respectively. Fragmentation by loss of CH3O˙ takes place at the thermochemical threshold for [CH3CO]+ formation for both isomers, which may therefore freely interconvert at internal energies corresponding to this decomposition threshold.
