Both conformers, //anti// and //gauche//, had about similar column densities, compatible with a kinetic temperature of 135 K. This agrees essentially with 150 K derived as rotational temperature of methyl acetate, which has a five times higher column density in this source than ethyl formate. | Both conformers, //anti// and //gauche//, had about similar column densities, compatible with a kinetic temperature of 135 K.
