A New Interstellar Polyatomic Molecule: Detection of Propynal in the Cold Cloud TMC-1
Abstract
The authors report the detection of the acetylene derivative propynal (HC ≡ CCHO) in the cold cloud TMC-1, with an abundance that is very close to that for the related species tricarbon monoxide (C3O). Propadienone, an isomer of propynal with the formula H2C = C = C = O, was not detected.
