Completed calculations for C2H2O4 (Oxalic Acid)
Methods and basis sets for which an energy has been calculated.
"e" indicates just an energy has been calculated.
"o" indicates an optimized geometry. "v" indicates vibrational frequencies.
"s" followed by a number indicates completed calculations for different states (for example s1ov).
"c" followed by a number indicates completed calculations for different conformations (for example c2ov).
See the Calculated Energies page
(section III.A.1) for more calculated properties.

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.
