Gaussian 16 is the latest in the Gaussian series of programs. It provides state-of-the-art capabilities for electronic structure modeling. Argonne’s Gaussian license covers all Argonne employess and students. All versions of Gaussian 16 contain every scientific/modeling feature, and none imposes any artificial limitations on calculations other than your computing resources and patience.
Note that the parallel execution environment TCP Linda 9 has changed in going from g09 to g16. The Link 0 commands %NProcLinda and %NProcShared have been depreceated and replace with the Link 0 commands %LindaWorkers and %CPU.
