# 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

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.
