In the present work a complete set of radiative transition rates is calculated for all for the O-like ions with . Energy levels, oscillator strengths and A values are computed for all transitions within the complex and are compared with previous calculations, where available. Calculations are carried out using the Superstructure code. The present work provides for the first time a self-consistent, complete set of A values necessary for the calculation of line emissivities and synthetic spectra for all the ions considered, filling several gaps in the existing literature. The present data are especially suited for the analysis of spectral lines emitted by the less-abundant elements in the universe, for which few if any data were available in the literature.
