The Computational Results Database
The Computational Results Database
The Computational Results Database currently contains over 113,000 entries covering 365 molecules and 41 atoms. It includes such items as:
• Molecular structures
• Harmonic frequencies
• Atomization energies, ionization energies, electron affinities
• Total energies
• Corresponding experimental values and references
• Theoretical references
Although the database covers a wide range of methods, such as density functional theory, Hartree-Fock and Moller-Plesset theory, the emphasis is on higher level methods that are capable of recovering a significant fraction of the correlation energy. These include complete active space configuration interaction wave functions and coupled cluster methods, such as CCSD(T), CCSDT and CCSDTQ. A limited number of full configuration interaction results are available.
New additions include explicitly correlated methods.
