Predicting bond angles via Energy Minimization (oleic acid in MMFF94)

This video demonstrates using MMFF94 to predict oleic acid's bond angle, and compares MMFF94's predicted bond angle with the prediction of other computational chemistry packages in ChemBio3D.

ChemBio3D offers two commonly accepted force field calculation methods, MM2 and MMFF94. These methods are designed so that you can calculate ...

MM2 Energy Minimization with hindered rotation

MM2 energy minimizations can identify more than one stable molecular conformation.

The MM2 force field method is available in all versions of ChemBio3D. MM2 is most commonly used for calculating properties of organic molecular models.

In ChemBio3D 11.0 and 12.0, the MM2 atom type is used for force field calculations. In ...
