Abstract
Explicit formulas for changes produced by a perturbation of a quantum‐mechanical system are given in terms of commutator brackets. Conditions that must be satisfied in order that these formulas be useful are discussed. Finally, it is shown how these new perturbation formulas are related to more usual ones in terms of energy denominators.Keywords
