Let (R, \mathfrakm, k) be a commutative Noetherian local ring. We study the suitable chains of semidualizing R-modules. We prove that when R is Artinian, the existence of a suitable chain of semidualizing modules of length n=max { i\geqslant 0 | \mathfrakmi ≠ 0 } implies that the the Poincar\acutee series of k and the Bass series of R have very specific forms. Also, in this case we show that the Bass numbers of R are strictly increasing. This gives an insight into the question of Huneke about the Bass numbers of R.
