On the determination of small electric dipole moments of excited electronic states in diatomic molecules

A new method is proposed for the determination of small electric-dipole moments in diatomic molecules by measuring the induced transitions due to crossed electric and magnetic fields. A theoretical treatment is given for states belonging to Hund's cases (a) and (b), and for states in the intermediate coupling case between Hund's cases (a) and (b). The method is restricted to non-Σ states.
