MolSys

This is a program for chemists and biochemists at University or Postgraduate level. Load cyclohexane as an example from the 48 molecules available (arginine, glucose and so forth). Now play around with all the facilities such as rotation, enlarging or shrinking the molecule, study bond angles from different atoms in the molecule, translate the atoms into bond energy fields, delete or substitute individual atoms and build up your own molecular structures from text book data. A second screen provides another panel of icons with radicals -Cl, -OH, methyl and many, many more to add to the molecule. Van der Waals energies may be calculated and text added to the molecule. Save to disk and build up your molecule - the program will not allow nonsense entries.
