Click here for the best view...     WinMopac7.21 is a powerful tool for semi-empirical calculations of chemical molecules. This program has combined an old DOS version MOPAC7 with some improvements which we have made, such as a convenient windows interface and an integrated external molecular viewer(RasWin). The interface includes all editing functions, a setting menu and some other features. This program is compatible with Windows XP, Vista and Windows 7 (both 32 and 64 bit). Also, it runs well under WINE in both Ubuntu and Macintosh versions.

    WinMopac7.21 is created by Dr. Roman Shchepin and Dmitriy Litvinov. We are especially thankful to Mikhail Andronov for his useful suggestions.

See below a list of free programs
which can be used together with WinMopac7.21:

ACD labs "ChemFolder" can be used for drawing of molecular structures and saving them as Mopac Internal format. These matrices can be opened by our program. ACD labs "ChemFolder" can be obtained from: ACD/Labs, registration is free.
Follow steps below:
1) Download and Install ChemSketch
2) Draw the structure in ChemSketch
3) Open 3D View (ACD/Labs - 3D view)
4) Come back to ChemSketch
5) Select the structure (edit-select all)
6) Copy the structure to 3D View
7) Add hydrogens and optimize structure (Tools - 3D optimization)
8) Save it in MOPAC Z-matrix to "Your name.dat"
9) Open the file with our program

Also, the output file produced by any other chemistry drawing software can be converted to MOPAC internal format by Open Babel
Old version of "Babel" and "BabelWin" can be obtained right from our web site:
Babel version 1.06 by Pat Walters and Matt Stahl - babel.zip
BabelWin by Dr. Jeffrey.J. Grosper and Mahmood Bhimji bw.zip
