What is it

CFT is a way of configuring, organizing the bonds of different metals and the ligands that bind to them. These bonds are seen as orbitals.

Below you can see the different configuration groups of orbitals referring to the material.

Here you can see the ligands and their fields.

With CFT you can describe the bonds of the orbitals and their geometric configurations.
