Abstract: The effects of diffusion in the atmospheres of subdwarf B stars have been investigated using a model atmosphere code which includes diffusion self-consistently. The impact of helium abundance profiles on the atmospheres of sdBs are presented. An examination of helium spectral lines in the models revealed the sensitivity of the profiles to abundance gradients. Possible diagnostics for detecting helium stratification in the atmospheres of sdBs are discussed.
