Computational Enhancements: (RED items not available in Essential Edition)
   
  Solvation Models SM6 and SS(V)PE continuum models now available.
     
  RI-CIS(D)

Resolution of the Image CIS(D) available with an order of magnitude speed increase for energy and a factor of 3 speed increase for structure [over CIS(D)].

     
  New DFT Functionals Non-empirical GGA functional PBE has been implemented. M05, M06, Slater-Dirac, Vokso-Wilk-Nusair, Perdew-Zunger, Wigner, Becke88, Gill96, Gilber-Gill99, Lee-Yang-Parr, Perdew86, GGA91, BMK, EDF1, and EDF2 are now available. Additionally, custom specification of exchange and correlation is included.
     
  Thermochemical Recipes The T1 procedure has been improved to provide heats of formation within 2 kJ/mol (RMSD) of G3(MP2) with speed and performance enhancements enabling routine calculations on molecules up to ~ 500 amu.
     
  NMR Improvements in the form of correction factors to C13 chemical shifts has been implemented reducing the mean absolute error to within ~ 2ppm.
