摘要

As part of an effort to study gas-grain chemical models in star-forming regions as they relate to molecules containing cyanide (- C equivalent to N) groups, we present here a search for the molecules 2- cyanoethanol (OHCH2CH2CN) and methoxyacetonitrile (CH3OCH2CN) in the galactic center region SgrB2. These 物種 are structural isomers of each other and are targeted to investigate the cross-coupling of pathways emanating from the photolysis products of methanol and ammonia with pathways involving cyano-containing molecules. Methanol and ammonia ices are two of the main repositories of the elements C, O, and N in cold clouds and understanding their link to cyanide chemistry could give important insights into prebiotic molecular 演化. Neither 物種 was positively detected, but the upper limits we det
