Atomic and molecular transitions for high Z objects in the early universe give bounds to the possible existence of extra spatial dimensions $D = 3+\epsilon$. We review the theory and present observational data, based on Lyman and Balmer hydrogen transitions of distant quasars and CO rotational transitions of far away giant molecular clouds.
