Scientific paper

In order to determine the location of the complex molecules CH3OH, CH2CHCN, HCOOCH3, CH3CH2CN, CH3CH2OH, and CH3OCH3 in the G34.3 +0.2 star-forming complex, BIMA Array observations of transitions near 104 and 107 GHz were carried out with 13" x 8" resolution. One site of complex molecule emission was detected. This core is located near the cometary H II region G34.3+0.2 C. The proximity of this core containing complex species to an ultracompact H II region is quite similar to the Sgr B2(N) core. This similarity suggests that, as appears to be the case in Sgr B2(N), a nearby, newly-formed massive star has evaporated grain mantles, releasing large amounts of complex species into the gas phase.
