Number of basis functions in CCCBDB for ()

These tables list the number of basis functions used in the calculations. For composite methods (G1, G2, G2MP2) the table lists the number of basis functions in the largest basis set. For methods not listed (such as MP2, QCISD, ...) the number of basis functions used in a calculation is the same as HF.
Methods with predefined basis sets

Methods with standard basis sets
For descriptions of the methods (AM1, HF, MP2, ...) and basis sets (3-21G, 3-21G*, 6-31G, ...) see the glossary in section I.C. Predefined means the basis set used is determined by the method.
