In principle, it is possible to solve the Schrödinger equation in either its time-dependent or time-independent form, as appropriate for the problem in hand; in practice, this is not possible except for very small systems.
U principu moguće je rešiti Šredingerove jednačinu bilo u njenoj vremenski-zavisnom ili vremenski nezavisnom obliku, u zavisnosti od studiranog problema, međutim u praksi to nije moguće osim za veoma male sisteme.
