We prove the integration by parts formula for abstract Wiener measures under much weaker conditions than those assumed in (11). Thus the formula holds for a much larger class of functions. For applications, we characterize the abstract Wiener measures, extend the Stein lemma to innite dimensions, and evaluate some functional integrals.
