Re: Solid state themodynamics

 The latest version of MOPAC 2000 has 3D periodic boundary conditions for
 handling solids. The author, Jimmy Stewart, has reported comparable
 accuracies to PM3 in the gas phase when calculating thermodynamic
 properties of solids during his limited testing to date. MOPAC 2000 also
 has d-orbital parameters for some transition metals. There is more
 information in the MOPAC 2000 User manual on-line at
 Hope this helps,
