IRIDIUM


Download for use in GAUSSIAN and COLUMBUS packages.

The following basis sets and potentials were taken from:


R.B. Ross, J.M. Powers, T. Atashroo, W.C. Ermler, L.A. LaJohn,
and P.A. Christiansen, J. Chem. Phys., 93, 6654 (1990).

Iridium Relativistic Effective Potential and Basis set including the 5d, 6s, and 6p subshells in the valence space. Note, the larger valence space potential will give more accurate results.
