Techniques have been developed to overcome the fact that orientable manifolds do not necessarily admit a Spinc structure. The authors point out that in the cases of primary interest in physics, orientable manifolds always admit Spinc structures, so that it is not really necessary to consider these more sophisticated techniques.
