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.

See section **III.C.1** List or set vibrational scaling factors
to change the scale factors used here.

See section **III.C.2**
Calculate a vibrational scaling factor for a given set of molecules
to determine the least squares best scaling factor.
