Abstract. In this article we prove the existence of bounded purely imaginary powers of the Stokes operator $ A_q $, which is defined on the space of solenoidal vector fields $ J_q(\Omega), 1 $ < q < $ \infty $, where $ \Omega={\hbox{\opens R}}^{n-1}\times (-1,1) $ is an infinite layer. It is a consequence of a special representation of the resolvent of the Stokes operator in terms of the Stokes operator on $ \mathbb{R}^n $, a composition of a trace and a Poisson operator – a singular Green operator – and a negligible part.
