On the theory of the Stark shifts of the rotational–vibrational levels of the hydrogen molecule and its isotopes produced by a point charge. II: HD, HT, and DT

Abstract

In continuation of paper I of this series on the homonuclear molecules H2, D2, and T2, the Hamiltonian describing the rotation and vibration of a heteronuclear molecule in the field of a point charge is given. Numercial results for the Stark shift of the molecular levels due to a point charge of either sign are listed for HD, HT, and DT as a function of the separation of this charge from the molecule. An application of the calculations to the charge-induced spectrum of HD is presented.
