✦ Synopsis

With the help of a simple semi-analytical procedure the oscillator strengths for Rydberg electronic transitions in the ArH molecule are calculated by accounting for the effects of non-spherical symmetry of the molecular coreΓ•s field due to its dipole moment. Such effects result in non-zero oscillator strength values for some transitions which are forbidden in the widely used atomlike model of molecular Rydberg states. For the allowed transitions we also report the difference between the atom-like calculations and the calculations which take into account the dipole moment of the molecular core.
