The website entitled COMFORT (https://ipc.iisc.ac.in/~ags/ip312/comfort.html) is a easy way to visualise fragment molecular orbitals of many different organic ligands and also metal fragments. One can match the frontier orbitals of the fragments to see if they can form stable molecules. It helps one to see how fragments of an octahedral organometallic complex can be stripped of its ligands one by one to generate fragments that can match organic ligands with multiple "pi" bonds. A basic understanding of Molecular Orbitals would go a long way in understanding how these web pages can be used.
Using any modern web browser, you can open the web pages of multiple fragments simultaneously in two different web pages instead of two tabs, you can place them side by side and compare the molecular orbitals. If you open them in two different tabs, just disconnect the tabs to see them side by side.
A description of how the website can be utilized is given in a YouTube video to help the student / faculty visualize the orbitals. The URL for the same is https://www.youtube.com/watch?v=WZ3-eGsOiBs
Visualizing the molecular orbitals of various fragments.
Understanding the symmetry properties of highest occupied and lowest unoccupied molecular orbitals.
Understanding the symmetry matching of the molecular orbitals of metal fragments and simple organic molecules.
All computational work carried out in these web pages were carried out using the Gaussian suite of programs and the results are visualized through pages created by WebMO. An excellent research for teaching MOs.
This looks like a great resource! I teach my students (the very basics of) WebMO in my junior/senior course, but they could use some benchmarked examples like these to see what their results are "supposed" to look like. Thank you for sharing this!
