GaussView software for Linux and Windows and gaussview for mac is a graphical interface for preparing Gaussian input files that is used to simulate a variety of molecules. This gaussview mac os software allows the user and chemists to graphically analyze the calculations with Gaussian software.
This software facilitates the preparation of complex input files for both routine and advanced calculations such as ONIOM, QST2 / QST3 optimizations, CASSCF calculations, Periodic Boundary Conditions (PBC) and many more. Also, if Gaussian is available on the same system as Gaussian View, you can start Gaussian calculations with it.
