Additional Spartan'06 Essential Features:

 
  List processing
Spartan automatically processes files comprising lists of molecules, in general operations applicable to a single molecule may be appplied to lists of molecules. Spartan is optimized to operate on lists of a hundreds of molecules (not thousands or tens of thousands).
     
  NOEs NOE data can be applied to confomrational searching as a post-processing filter.
     
  On-line Infrared data If your computer has internet connectivity, Spartan'06 Essential can retieve and plot experimental IR (~ 14,000 molecules) spectra from the NIST Chemistry Webbook.
     
  On-line PDB Access Spartan'06 Essential can retrieve protein and nucleotide structures from the RCSB Protein Data Bank via PDB-ID.
     
  Constraints and Frozen Atoms Geometry optimization and conformational analysis are available subject to user specified constraints (of distance, angle, or torsion angle) and/or frozen atoms.
     
  User Generated Database Parallel to the Spartan Molecular Database, user's can save Spartan data in the .spentry format (Spartan Molecular Database format) and construct custom databases, extend the computational models, and number of molecules available from within Spartan.
     
  New Alignment Feature
An improved algorithm for molecular alignment is available, alignment scores may be posted to the Spartan Spreadsheet.
