摘要

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.
