Gaussian 16W is a molecular modeling software package that is widely used in chemistry, physics, and materials science. It is a commercial software product developed by Gaussian, Inc. and is considered one of the most popular and powerful computational chemistry tools available.
Advanced models like SMD and PCM to simulate how molecules behave inside liquids and solutions.
Gaussian 16W is a native 64-bit Windows application . It does not require WSL or Cygwin. However, for large MP2, CCSD, or TD-DFT calculations, the Windows version is significantly slower than Linux. Many "top" users dual-boot or run Linux VMs. It seamlessly brings the power of electronic structure
