Winmostar is a GUI software which provides versatile tools as pre- and post- processor for the standard applications of computational chemistry such as MOPAC, GAMESS or Gaussian. This software will help you to construct molecular models and input data files with necessary key words that you want to feed into those applications.

Winmostar will provide you a comfortable work space on your windows PC with quick-responding graphical UI. It is as easy as writing chemical formula on your note book. Even untrained researchers will find no difficulties or no frustrations.

Winmostar is also a powerful tool to visualize the results provided from the computation programs. You can check your molecule from various aspects in 2D and 3D. You can also use VRML viewer to visualize molecular structures together with their orbital images, electrostatic potentials and other aspects of the molecules.

Winmostar was created and has been kept up by Senda. He was nominated as IPA's Super Creator Program in 2004. The software was publically introduced as "Recommended software for Student of engineering course"
