  "abstract": "The first rotational study of cyclopentadiene oxide (C5H6O, CPO) is presented. Three spectrometers were employed for measurements between 11.5 and 500 GHz. In these measurements, 1986 lines could be assigned, whose quantum numbers ranged to a maximum value of J = 75 and Ka = 56. Quantum chemical calculations were performed and provided starting values for deriving spectroscopic parameters. Rotational parameters, as well as quartic and sextic distortion parameters, are presented which shall enable an astronomical search of this heterobicycle.",
