Abstract | A minimal basis set of localized quasiatomic orbitals for Mo is constructed using the fully converged eigenstates from first-principles calculations with a large basis set. The orbitals, although similar in shape to those of a free atom, are slightly deformed such that it can reproduce all the occupied-state electronic properties of the system. They are very useful for analyzing chemical bonding by calculating the Mulliken overlap population and bond order index between atoms. In addition, the transferability of tight-binding parametrizations can be evaluated, for example, the effect of the two-center approximation. |
