Reaction of AsCl3 with Cl2 at low temp yields a product, believed to be AsCl5, which shows Raman bands at 437,369,295,220,213, and 83 cm-1. Detailed analysis of the 369 and 295 cm-1 bands show them to arise from totally symmetric modes. Show that the Raman spectrum is consistent with a trigonal-bipyrimidal geometry.
