Linear Combination of Atomic Orbitals

Click For Summary

Homework Help Overview

The discussion revolves around the Linear Combination of Atomic Orbitals (LCAO) approximation, which is a concept in quantum chemistry related to the formation of molecular orbitals. The original poster seeks additional resources to understand this topic better, as the class text and reference materials are deemed insufficient.

Discussion Character

  • Exploratory, Conceptual clarification

Approaches and Questions Raised

  • Participants discuss various reference texts that may provide insights into the LCAO approximation. Some express uncertainty about the coverage of the topic in specific texts, while others suggest looking for chemistry-oriented resources.

Discussion Status

Several participants have provided a list of potential references, indicating a collaborative effort to assist the original poster. There is an ongoing exploration of which texts might be most helpful, with some participants expressing doubt about the availability of information in certain books.

Contextual Notes

Participants mention that certain topics, such as Huckel Theory and EHT, were skipped in their coursework, which may affect their understanding of LCAO. The original poster does not have access to all suggested texts, which may limit their ability to verify the information discussed.

Is anybody familiar with LCAO approximation? I'm working on my last problem for this assignment and the class text doesn't really cover it enough for me nor do my reference texts cover it enough. Does anybody know any good references so I can read more on LCAO approximation? Thanks.

The 2 volumes of Cohen-Tannoudji on Quantum Mechanics certainly cover chemical bonds...

You must find something there,i'm sure.

And it wouldn't hurt checking online reference,as well.Just google LCAO.

Hmm, I have the Dirac text on my bookshelf. I will go back and look through it. Thanks!
 
If u don't find it in Dirac's text,then choose another one,preferably chemistry oriented.

You mean Huckel Theory and EHT? We skipped that section in our P. Chem class.
 
That's exactly what he meant.You probably did Heitler-London's theory.

That's not what I was hoping to hear. I'll check the Dirac text.
 
I don't have the book by Dirac.So that's why i couldn't tell if it was there or not.For what it's worth,i doubt it.

Daniel.
