Abstract
In Appendix, we have an analytical investigation of the well-known 10-12 potential
of hydrogen-hydrogen covalent bond. In this research, we will make an elaboration of the well-known 6-12 Lennard-Jones potential in case of this type of bond. Though the results are
illustrated in many text books and literature, an analytical analysis of these potentials is missing
almost everywhere. The power laws are valid for small radial distances, which are calculated
to some extent. The internuclear separation as well as the binding energy of the hydrogen
molecule are evaluated with success.
