It is essential to know the space-time structure of the nonlocal vacuum condensates for application to medium energy processes. Using the Dyson-Schwinger formalism in the rainbow approximation for the quark propagator, we study the nonlocal quark condensate and model forms for the nonper-turbative gluon propagator constrained by ts to local condensates and deep inelastic scattering with nucleon targets.
