Bond Properties

---

To define bond properties of selected bonds in a structure:

1. Do one of the following:

• Select a bond using a selection tool.
• Shift+click to select multiple bonds.

2. Do one of the following:

• Right-click, point to Bond, point to the property you want, and then choose the appropriate option.
• From the Structure menu, choose Properties. On the Bond Properties tab, select the bond properties to associate with the selected bonds from the drop-down lists. Click OK.
• Point to an bond and press the HotKey "/ ". In the Bond Properties dialog box, select the properties to associate with the selected atoms. Click OK.

Query indicators appear next to bonds that have associated bond properties.

The characters that appears depends on which query properties have been assigned. If more than one property is assigned, more than one descriptor appears adjacent to the atoms. For more information, see "Query Indicators".

The indicators are described in the following table.

Any	Bond Type: Any
S/D	Bond Type: Single/Double
D/A	Bond Type: Double/Aromatic
S/A	Bond Type: Single/Aromatic
