[edit] Overlap Integral

Wikipedia doesn't seem to have a reference to "overlap interval" which is required by the "Linear combination of atomic orbitals molecular orbital method". "Overlap integral" accounts for overlap in atomic orbital wavefunctions. My reference, "Tinkham M, Group Theory and Quantum Mechanics, Dover, 2003, page 214" illustrates the use of the overlap integral in a specific example. A more general description is needed. 150.203.2.85 01:18, 30 November 2005 (UTC)

I have now found a definition from the Glossary of Terms Used in Theoretical Organic Chemistry provided by the International Union Of Pure and Applied Chemistry (http://www.iupac.org/reports/1999/7110minkin/o.html):

Overlap integral - The integral defining the summation over the space of the overlap of the electron density of two orbitals. 150.203.2.85 01:32, 30 November 2005 (UTC)
