NIOBDIUM


Download for use in GAUSSIAN and COLUMBUS packages.

The following basis sets and potentials were taken from:


L.A. LaJohn, P.A. Christiansen, R.B. Ross, T. Atashroo,
and W.C. Ermler, J. Chem. Phys., 87, 2812 (1987).

Niobium Relativistic Effective Potential and Basis set including only the 5s and 4d subshells in the valence space. Note, the larger valence space potential will give more accurate results.
