Understanding the physics of the photodissociation regions (PDRs) which occur between the ionized HII regions and the surrounding molecular clouds is critical in assessing the role that primary star formation has on secondary events. It is also pivotal to understanding how HII regions affect their local environment. Modelling of these interfaces, and of the photons that escape to ionize the local ISM, has been hampered by a lack of modern models of the O-star atmospheres. We present preliminary results from a program intended to better model the physics of the extended atmospheres of O stars and thus derive more physically accurate photon fluxes and therefore better estimates of the actual ionization rates. The models include features such as winds, spherical symmetry, accurate and up-to-date opacites, and the effect of metallicity on the extended envelope of material around O stars and the spectra that emerge from them.
