Talk:Basis set (chemistry)

To do:

add some equations for the Gaussians, illustrating the origin of "zeta" in double, triple-zeta
an example basis set for a lighter atom

"This" and "these" as subjects make articles difficult to understand

"this led to huge computational savings…"
"This adds some additional…."
This is an important result when considering accurate…."
"The smallest of these are called …"
"These are auxiliary functions …"
"These are very shallow Gaussian…"

Minimal Basis Set

This article doesn't really address the subject of a minimal basis set correctly. The section claiming to do so seems to address Slater-type Orbitals (STO). A minimal basis set is one which accomodates all the electrons in the ground state and completes the shell thereafter. (Szabo & Ostlund, Modern Quantum Chemistry, Dover, 1989 p. 184) This can be done with Slater orbitals, Gaussian orbitals, etc. --L. Belcher

Dunning's basis sets

"The 'cc-p', stands for 'correlation-consistent polarized' and the 'V' indicates they are valence-only basis sets"

Valence only? I'm not so sure... I think 'cc-pV' should be read 'correlation consistent' and 'polarized valence'. As the article is written now it sounds like the non-valence orbitals aren't described at all in these basis sets. — Preceding unsigned comment added by 128.178.54.111 (talk) 13:49, 17 June 2013 (UTC)[reply]

Effective Core Potentials

Would anyone be willing to write something about effective core potential basis sets such as LANL2DZ and SDD? That article is quite physics heavy. It's quite common for chemists to used ECPs for metals and Pople type basis sets for ligands but I think few people who actually do this understand what an ECP is (including me).Pelirojopajaro (talk) 22:14, 15 February 2017 (UTC)[reply]

LAPW basis sets

The article is missing a section on LAPW basis sets. I will add one. I hope, this is okay. If you believe it can be improved, feel free to do so or make a comment in this discussion so that I or someone else can include your improvements. GreSebMic (talk) 14:47, 7 April 2023 (UTC)[reply]
