For many years it has bugged me that we never show students any experimental data to compare to the calculated energy levels of a one-dimensional infinite square well. Does anyone know of such data? Obviously the 1-D infinite well involves many idealizations that will hold only approximately for actual physical systems, natural or fabricated. But the essential result, it seems to me, is a quantum ladder of energy levels that get farther apart as you go up. Can anyone point me to an experimental energy level diagram that has this property?
