When carbon suboxide was flash-photolyzed isothermally the ultra-violet absorption spectrum of the C3 radical at 4050 Å was observed strongly at short delay times. In addition, a series of new diffuse systems were detected in the wavelength regions 4300–4450 Å, 3400–3700 Å, 3100–3300 Å and a strong continuous absorption extending from 3100 Å to shorter wavelengths. The effect of CO2, O2, N2, Ar, NO, CO, C2H2 and C2H4 on these systems has been investigated and the results obtained indicate that the new systems are due to either the singlet C2O radical or some species produced in the fast reaction of C2O (singlet) with C3O2. The reactions of O1D and O3P with C3O2 and those of C2O (singlet) with O3, NO2 and CN have also been investigated.
