• Resumen

  • A system for construction of simple poster-board models is described. The models dynamically demonstrate the symmetry operations of proper rotation, improper rotation, reflection, and inversion for the chemically important point groups D3h, D4h, D5h, D6h, Td, and Oh. The models also clearly show where the applicable point, line, or plane lies in relation to the other symmetry elements. This method is presented for use as a one-period exercise in the laboratory course that traditionally accompanies the third- or fourth-year undergraduate-level (advanced) inorganic chemistry lecture course.
