Gaussian 09 is the up-to-date version of the software and is licensed for the campus use.
Gaussian is a series of electronic structure programs which is designed to model a broad range of molecular systems under a variety of conditions. Gaussian performs its computations starting from the basic laws of quantum mechanics.
Gaussian is used by chemists, physicists and engineers for research in established and emerging areas of chemical interest, studying molecules and reactions of definite or potential interest, including both stable species and compounds which are difficult or impossible to observe experimentally: short-lived intermediates, transition structures etc.
Gaussian 09 can be run on Linux platforms (on Intel EM64T veya Intel Itanium2 IA64 architecture) and in parallel environment (PC Clusters) with these processors. Gaussian 09 can be downloaded from
Gaussian 09 can be used in parallel environment, at the PC Cluster at METU-CC, to benefit from high performence computing capabilities. The PC cluster is administered by ULAKBIM High Performance and Grid Computing Center (TR-Grid). To use softwre on TR-Grid a membership is required.
