Spartan Molecular Properties: In addition to energies, equilibrium and transition-state geometries and frequencies, Spartan'06 Essential provides a number of useful properties.
   
  Atomic Charges Mulliken and Natural Bond Orbital Charges are available as are charges based on fits to electrostatic potentials.
     
  Thermodynamics Enthalpies, entropies and free energies as well as isotope effects, based on calculated geometries and IR vibrational frequencies.
     
  Electrical Dipole, polarizabilities (hyperpolarizabilities from SemiEmpirical methods).
     
  Additional Properties Weight, Area, Volume, Symmetry Group, HOMO and LUMO Energies, Polar Surface Area, LogP, Ovality, Q-Minus, Q-Plus, Electronegativity and Hardness.
     
  Solvation

Aqueous solvation energies from SM5.4 or SM50R models.
