What can this tool predict?

It predicts d-electron configurations, magnetic properties (paramagnetic/diamagnetic), molecular geometry, and the observed color of transition metal complexes.

Does it account for Jahn-Teller distortion?

Yes, the `determine_geometry_and_splitting` tool identifies if a complex is subject to Jahn-Teller distortion.

How do I find the color of a complex?

You can use the `predict_optical_properties` tool by providing the d-electron count, spin state, and splitting magnitude.
