In this paper some significant aspects of the evolution of solid-state spectroscopy in Pavia are briefly reviewed in their
basic lines starting from the '50s. As an example of historical trends and scientific developments, the authors describe and
discuss two experiments on low-dimensional systems which, over a period of nearly three decades, represent a coherent approach
to spectroscopic disciplines.
