“…A spectral analysis program, MacLoomis (McNaughton et al 1991), was used to help assign the spectral lines by vertically stacking lines with the same K a or K c values. A total of 1182 lines were assigned between 15 and 73 cm −1 .…”

High-resolution FTIR spectra of ethylene oxide have been measured in the far-infrared region using synchrotron radiation. A total of 1182 lines between 15 and 73 cm −1 were assigned, with J max = 64, expanding upon previous studies that had recorded spectra up to 12 cm −1 , J max = 49. All available data were co-fitted to provide greatly improved rotational constants for the ground vibrational state that are capable of predicting transitions up to 73 cm −1 .

“…In previous laboratory investigations the C 3 O molecule was produced either by glow discharge of carbon suboxide, C 3 O 2 , (Tang et al 1985) or by pyrolytic processes, employing various stable precursors (Brown et al 1983;Klebsch et al 1985;Brown et al 1985;McNaughton et al 1991). In the present investigation we found it convenient to produce C 3 O by flow-pyrolysis of fumaryl chloride (Aldrich), using the same apparatus already employed to generate HC 5 N (Yamada et al 2004) and HC 7 N (Bizzocchi & Degli Esposti 2004).…”

“…12 mTorr (≈2 Pa) inside the absorption cell. However, even in the best conditions, the recorded spectra were very often contaminated by several interfering lines produced by the unreacted precursors and by the various side products of the pyrolysis process, the most prominent of which are chloroacetylene, chlorodiacetylene, and 2-propynoyl chloride (McNaughton et al 1991). These features are in general weaker than the most intense C 3 O lines, but they are still a considerable drawback when the faint spectra of the vibrationally excited states are sought for.…”

“…Later, its ground-state millimetre-wave (mm-wave) spectrum was also recorded (Tang et al 1985;Klebsch et al 1985), and a high-resolution infrared study of the ν 1 and some associated hot bands has been performed using Fourier transform infrared spectroscopy (FTIR) (McNaughton et al 1991).…”

“…Few low-J rotational lines of the v 5 = 1 bending state were recorded by Brown et al (1985), while for the v 5 = 2 and v 5 = 3 overtone states the only available spectroscopic data are those derived from the rovibrational bandby-band analysis of the ν 1 hot band system (McNaughton et al 1991). The ν 5 bending mode of C 3 O has an energy of 114 cm −1 (Hochlaf 2001), thus the first members of its vibrational ladder might be populated by the radiative pumping mechanism occurring in IRC+10216, which is one of the brightest objects of Article published by EDP Sciences the infrared sky.…”

The submillimetre-wave spectrum of C 3 O (X 1 Σ + ) has been investigated in the laboratory using a source-modulation microwave spectrometer equipped with a gas-phase flow pyrolysis system for the production of unstable chemical species. C 3 O was produced by thermal decomposition of fumaryl chloride at 900• C. Thirty-seven new rotational transitions were observed in the frequency range 307-740 GHz for the ground vibrational state, reaching a J quantum number as high as 76. Additionally, new millimetre-wave and submillimetre-wave lines were recorded for the bending fundamental v 5 = 1, and for its overtones v 5 = 2 and v 5 = 3 whose rotational spectra have been identified for the first time. The new laboratory measurements provide much improved rest frequencies in the submillimetre spectral region for the ground state spectra of C 3 O, and for the first levels of its low-energy v 5 vibrational ladder, useful for the radioastronomical identification of their rotational lines in the ISM.
