I developed this Jmol page to help my students see the relationship(s) between the ligands and metal d-orbitals in a number of different geometries. Since the images are all rotatable, students who have difficulty looking at flat images and drawing appropriate conclusions have that barrier reduced or eliminated. I have now used the application twice - this past fall in the second semester of introductory chemistry and a few weeks ago when I began ligand field theory in my inorganic course. In both classes I received favorable comments. A number of students in the inorganic course, who had not had me in previous courses, remarked that they wish that they had seen this in their introductory course.
