The complexes are low-spin, closed-shell, and I'm wondering what theoretical model might give reasonable predictions for the ligand's vibrational frequencies. Any experience with this problem or pointers to published articles would be appreciated. Thanks, -Alan ==== Alan Shusterman Department of Chemistry Reed College 3203 S.E.
