On 'infinite basis set limits' in molecular electronic structure calculations
1Rutherford Appleton Laboratory, Chilton, Oxfordshire, UK.
Abstract:
Sequences of basis sets can be constructed so as to approach the 'infinite basis set limit' in molecular electronic structure calculations. Extrapolation procedures can also be devized to provide accurate values of this limit. However, some care is required since the 'infinite basis set limit' may not correspond to the limit supported by a complete basis set. Extrapolation procedures can then lead to limiting values, which are not estimates of the exact solutions.

Molecular Orbital Theory II
Electronic Structure of Atoms
An atom comprises protons and neutrons, which are contained inside the dense, central core called the nucleus, with electrons present around the nucleus. Taking into account the wave–particle duality of electrons and the uncertainty in position around the nucleus, quantum mechanics provides a more accurate model for the atomic structure. It describes atomic orbitals as the regions around the nucleus where electrons of discrete energy exist, characterized by four quantum numbers: n, l, ml, and...
