WebbThe Hückel Hamiltonian is an incredibly simple tight-binding model famed for its ability to capture qualitative physics phenomena arising from electron interactions in molecules and materials. Part of its simplicity arises from using only two types of empirically fit physics-motivated parameters: the first describes the orbital http://chemistry.du.ac.in/study_material/4305/HMO_Theory_Part_4.pdf
WebbI. RECAP OF HUCKEL THEORY¨ We begin with a brief recap of Hu¨ckel theory, taking initially the practical viewpoint of ‘how-to-do’ calculations, rather than the ‘meaning’ of the subject. We will later return to this latter aspect. This approach, I hope, will have the advantage of getting you started on familiar ground. WebbA: The molecule given is TeF4.
