A new interstellar polyatomic molecule - Detection of propynal in the cold cloud TMC-1The detection of the acetylene derivative propynal in the cold cloud TMC-1, with an abundance that is very close to that for the related species tricarbon monoxide, is reported. Propadienone, an isomer of propynal, was not detected and is hence less abundant than either C3O or HC2CHO.
