Abstract
A rotationally resolved infrared spectrum of the transient molecule propadienone has been recorded in a low temperature jet using diode laser absorption spectroscopy. The molecule was generated by pyrolysis of acrylic anhydride. The spectrum arises from the intense C–O stretching mode of the molecule and several series of lines were identified using Loomis Wood plots. The most prominent series on the high frequency side of the band origin consists of both a- and b-type transitions.
