Abstract
Molecular scattering of radiation in the expanding universe at redshif ts z from 30 to 50 is considered. It is shown that the presence of mol ecules like H-2D+ can create a ''curtain'' that blurs the primordial s patial fluctuations of the cosmic background radiation (CBR). The requ ired abundances for this molecule are estimated and features of the se condary fluctuations are discussed.
