If you have the Chime plugin correctly loaded, you should see a molecule and some buttons below:

Identify Atoms Bond Length Bond Angle Dihedral Angle (Torsion Angle)

Rotating Models:
Place your cursor in the Chime window, click and hold the mouse button and move the cursor

Model Display:
Windows: Right-click on the Chime window to access an options menu. (Macintosh: Click and hold on the Chime window.) Use the Display submenu to change the model display.

Identify Atoms:
Click the button next to "Identify Atoms" and then click any atom in the Chime window. The atom label will appear in the text box below the buttons.

Bond Length:
Click the button next to "Bond Length" and then click any two atoms. The distance between those atoms will appear in the text box (in units of Angstroms).

Bond Angle:
Click the button next to "Bond Angle" and then click any three atoms. (In the example, click C, O, and H in that order.) The corresponding bond angle will appear in the text box.

Dihedral Angle (Torsion Angle):
Click the button next to "Dihedral Angle" and then click any four atoms. (In the example, click H, C, O, and H in that order.) The corresponding dihedral angle will appear in the text box.

Note: The most recent function remains active until you click another button.
