Abstract
The various expressions for oscillator strengths and rotational strengths are examined within the context of Hartree–Fock theory. They are shown to be inequivalent. The f‐sum rule, rotational sum rule, and the origin dependence of rotational strengths are also examined. It is shown that the time‐dependent Hartree–Fock theory removes the difficulties.Keywords
