摘要：

Three of the less common oxides of carbon, OC2O, OC3O and C2O, have been studied by tandem mass spectrometric methods. Neutralization-reionization (NR) mass spectrometry provided evidence for the possible generation of (hitherto unobserved) stable OC2O molecules having a lifetime of at least 1 mus. Ionized OC3O and C2O both produced stable neutral species in their NR mass spectra in keeping with their known chemistry. The heats of formation of OC2O.+ and C2O.+ were measured to be 940 +/- 10 and 1412 +/- 5 kJ mol-1, the latter in good agreement with earlier work.
