- In chemistry, wedges and dashes are used to represent the three-dimensional structure of molecules on two-dimensional surfaces1234:
- Wedges represent bonds and atoms coming forward from the backbone plane.
- Dashes represent bonds and atoms going backward from the backbone plane.
- In dash-wedge structures, all atoms and bonds are shown.
