WebAtom-centered, Gaussian basis sets were used : the Pople-style 6-31G(d) sets for lighter atoms (Z ≤ 36; up to Kr) and the Stuttgart-Dresden ("SDD") pseudopotentials and matching basis sets for heavier atoms. WebNov 24, 2024 · It is also sometimes written as 6–311++G (d,p). There are also double split valence basis sets like 6–31+G*. Choosing them in GAMESS is a bit difficult. If the basis set is x-yz type then use GBASIS=Nyz and NGAUSS=x. So for 6–31G it would be GBASIS=N31 and NGAUSS=6. For 6–311G it would be GBASIS=N311 and NGAUSS=6. dungeons and diners and dragons and dives
