- Point group
- C∞v — A linear molecule without a centre of inversion: a C∞ axis along the bonds and an infinite number of mirror planes containing it.
- Order
- ∞
- Operations
- E, 2C∞, ∞σᵥ
- Shape
- Linear
- Atoms
- 3 (O, C, S)
Symmetry elements of OCS
- C∞ — the molecular axis: any rotation leaves the molecule unchanged
- σᵥ (one of ∞) — any plane containing the axis
- σᵥ (another) — any plane containing the axis
Structure
- C=O 1.16 Å, C=S 1.56 Å
- O=C=S 180°
- Two different ends, so no inversion centre
