Scientific paper

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.
