We have calculated a variety of mesonic and baryonic correlation function using an instant on model of the QCD vacuum. These correlation functions can be used to determine the spectrum of physical states in each channel. The short distance behavior of the correlators is interesting in comparison with predictions from QCD sum rules based on the Operator Product Expansion. We find that the model not only predicts the masses and coupling constants of the lowest resonance in most channels but also reproduces the first lattice measurements of QCD point to point correlation functions.
