A DIPOLE-MOMENT FUNCTION OF MeH MOLECULES (Me = Li, Na, K))

The dipole-moment functions of the ground states of LiH, NaH, and KH molecules at small internuclear separations are calculated. Based on these calculations, the dipole-moment functions of molecules under consideration are derived for a wide range of internuclear separations. To this end, use was made of the cubic spline interpolation of the dipole-moment functions calculated in this work and those known ab initio.
