Basis sets acronyms

• SZ: single zeta
• DZ: double zeta
• DZP: double zeta + 1 polarization function
• TZP: valence triple zeta + 1 polarization function
• TZ2P: valence triple zeta + 2 polarization function
• TZ2P+: = TZ2P + extra d (3d metals) or extra f (lanthanides)
• pVQZ, QZ3P: valence quadruple zeta + 3 polarization function, even tempered
• QZ3P-nD: = QZ3P + n diffuse sets of s, p, d, and f functions, even tempered
• QZ4P: valence quadruple zeta + 4 polarization function, relativistically optimized
• ASZ, ADZ, ADZP, ATZP, ATZ2P: augmented for use in TDDFT

For small negatively charged atoms or molecules, like F⁻ or OH⁻, use basis sets with extra diffuse functions, like the augmented or QZ3P-nD
