Modeling a variety of topics related to computational chemistry Has a large number of important and basic algorithms The Windows version of Gaussian can run as a single-processor or multi-processor. A 32-bit version of the single CPU is also available to researchers as a light version with an IM extension, such as 09IM. Gaussian has many capabilities in modeling electronic structures, the Windows version of this software has the extension w (such as 09w) and also for Mac PCs based on power pc software will have the extension m. Professor Pople and his students used the capabilities of this software to do good research in quantum chemistry and other disciplines that demonstrate the practical application of this product. The program was created by Professor John Pople and his research team at the University of Mellon. The first version of this program was released in 1970, but over time it became one of the most popular programs in the field of computational chemistry. Gaussian is software for computational chemists.
