Spartan includes access to a number of highly useful molecular databases, including: The Spartan Molecular Database, Spartan Reaction Database, Cambridge Structural Database* and Protein Data Bank**. (Items in BLUE are available with Parallel with the Spartan'16 Parallel Suite)

*CSD must be licensed separately. **PDB access requires internet connectivity.

  Databases:  
     
  SSPD* The SSPD is a collection of >275,000 molecules that includes highly accurate structures, energies, properties, and IR (EDF2 only) and NMR spectra as well as the molecule's wavefunction for auto-generation of graphical surfaces. Both the EDF2 and wB97X-D

*Spartan'16 includes a subset of >6,000 molecules. The full SSPD (and SMD) are available with the Spartan'16 Parallel Suite.
     
  SMD Access and retrieve/replace constructed or imported structures from a library of 150,000* molecules, pre-calculated at up to 5 quantum theory levels: HF/3-21G, HF/6-31G*, EDF1/6-31G*, B3LYP/6-31G*, and MP2/6-31G* models. Retrieved data includes: the name, equilibrium geometry, gas-phase energy, estimated (aqueous) solvation energy, HOMO and LUMO energies, dipole moments, electrostatic-fit atomic charges, surface area, polar surface area, volume, weight, symmetry, and spectra data.
     
  SRD Access to exact and substructure searching of the Spartan Reaction Database of more than 1500 reaction types for providing initial structure guesses for transition state geometry calculations.
     
  SIRD The Spartan Infrared Database allows for searching the SSPD using an experimental infrared spectra as the query. Hits are retrieved and scored based on the similarity of the query to calculate infrared spectra.
     
  CSD Accesses the Cambridge Structural Database (CSD)* of over 800,000 experimental X-ray crystal structures for organic and organometallic molecules, together with their literature references. Spartan optionally adds hydrogens and refines hydrogen positions.

*CSD may be licensed from the Cambridge Crystallographic Data Centre or one of its distributors.
     
  PDB Spartan can retrieve (based on PDB ID) entries from RCSB PDB (provided your computer has current internet connectivity). The Protein Data Bank includes more than 118,000 x-ray crystal and NMR structures of proteins and nucleic acids. Band ligands may be extracted.
