Slater-type orbital
From Free net 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
- <math>R(r) = A r^l e^{-\alpha |\textbf{r}-\textbf{a}|}</math>,
where <math>l</math> is the angular momentum quantum number, A is a normalization constant, <math>\textbf{a}</math> is the position vector of the atomic nucleus and <math>\alpha</math> is a constant related to the effective charge of the atom in question.
They are named for physicist/chemist John C. Slater.
