The Bonds Conformation expression

You must provide the name of the group or groups for the evaluator to analyze. The group name must be either:
- A shortcut group name that MarvinSketch recognizes when you type it, such as Me, iBu, or OPh.
- A SMILES definition, such as O (for OH), Br, or C(C)C (for iPr) without any numerals or bound H atoms. See the on-screen instructions (shown in the image below) for more detail.
