Millimeter observations of organic molecules toward high-mass star formation region G34.26+0.15

Li Fu, Guo-Man Lin


Abstract To investigate the chemical origination of organic molecules CH3OH, CH3OCH3, C2H5OH, CH3OCH, CH3CN, C2H3CN and C2H5CN in the hot core associated with high-mass star formation region G34.26+0.15, Submillimeter Array observations were made with its 230 GHz receiver. The molecular gas distribution has shown that the oxygen- and nitrogen-containing molecules peak at different positions. Comparing the spatial distributions with rotational temperatures and fractional abundances of the observed molecules, we discuss the possible chemical origination of these organic molecules.
