Scientific paper

We propose to search for methyl acetate, CH3COOCH3, in high mass hot cores. Methyl acetate is possibly synthesized through multiple reaction pathways from molecules previously detected in hot cores, most notably from acetic acid and methanol via esterification. Esterification, beyond the formation of methyl formate, has not yet been observed in the ISM. The project is already underway in nothern sources based on millimeter data from the Caltech Submillimeter Observatory (CSO). We hope to study the chemically rich southern source G327.3 (decl B1950=-54.49'15.6"), amongst others, using MOPRA and to search for acetic acid and methyl acetate. Observations are supported by laboratory studies of methyl acetate in the 3 mm and 1 mm and successful spectral fitting by the Blake group at Caltech. If detected, methyl acetate, consisting of 11 atoms, would be one of the larger complex organic molecules detected in the interstellar medium and could point to previously unconsidered reaction mechanisms.
