We consider some properties of the spectral expansions related to selfadjoint extensions of the operator Hu -----u" + q(x)u over the whole line R in the case when q(x) is a continuous periodic function (the Hill operator) and in the case when q(x) is a bounded measurable function. This paper gives a
