Abstract
We present a perturbative study of Ramond-Ramond backgrounds in the NSR for malism. We show how to perform sigma -model computations and discuss in det ail the structure of the BRST charge and picture changing operators. Contac t terms play a vital role in the analysis. We also give evidence for a two loop nonrenormalization theorem for the background beta functions.
