We investigate constraints on embeddings of a nonorientable surface in a 4–manifold with the homology of M I , where M is a rational homology 3–sphere. The constraints take the form of inequalities involving the genus and normal Euler class of the surface, and either the Ozsvath–Szabo d –invariants or Atiyah–Singer – invariants of M . One consequence is that the minimal genus of a smoothly embedded surface in L.2k; q/ I is the same as the minimal genus of a surface in L.2k; q/ . We also consider embeddings of nonorientable surfaces in closed 4–manifolds.
