Slater-type orbital

From Wikipedia, the free encyclopedia

Slater-type orbitals (STOs) are functions used as atomic orbitals in the linear combination of atomic orbitals molecular orbital method. They are distinguished by the form of their radial component, which is given by

R(r) = Ar^le ^{− αr}

where

l is the angular momentum quantum number,

A is a normalization constant,

r is the distance of the electron from the atomic nucleus, and

α is a constant related to the effective charge of the atom in question.

They are named for physicist/chemist John C. Slater.
