Question

SbCls can exist as two different modifications in the solid state: a) as an ionic salt made of tetrahedral [SbCl]* cations and octahedral (SCI) anions or b) as molecular dimers of edge-sharing octahedra C1 Sb(H-CI),SbC14, Analyze the Sb-Cl stretching vibrations and answer whether you can distinguish the two forms by IR only, Raman only, or you need both IR and Raman.
