Abstract
Ethyl cyanide (CH3CH2CN) emission and absorption have been imaged with the Very Large Array toward Sagittarius B2(N-LMH) by means of the 515-414 rotational transition at 43.5 GHz (λ ~ 7 mm). The 15 × 14 VLA beam shows two principal sources of ethyl cyanide emission: an unresolved source ~5'' north of the LMH that is kinematically consistent with simple expansion, contraction, or small-scale turbulence, and the resolved LMH core source itself that shows kinematics indicating an edge-on rotating disk that extends ≥3'' (~0.1 pc) in the approximate east-west direction. A search for the 707-606 rotational transition of the amino acid glycine (NH2CH2COOH) at 43.7 GHz toward Sgr B2(N-LMH) gave negative results.
