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 1".5x1".4 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 7₀₇-6₀₆rotational transition of the amino acid glycine (NH₂CH₂COOH) at 43.7 GHz toward Sgr B2(N-LMH) gave negative results.
