The conformal anomaly has provided an expression for the effective action of gauge theories in the presence of a strong background field in terms of the running coupling constant. We exploit this result to find a novel expansion for the running coupling constant and to compare it with conventional expansions obtained by directly integrating the differential equation for the running coupling constant.
