This property is possessed by every entity described by the eleven Laue (“LAO-uh”) classes. Elements describing this property are found in the top row of 2D diagrams labelled with Mulliken symbols. (15[1])A molecule’s LCAO can be determined by applying projection (15[1])operators on each stretching vector to generate “adapted linear combinations” (15[1])named for this (15[1])property. (-5[1])Molecular orbitals are described as (*) gerade (10[1])(“guh-RAH-duh”) when they (10[1])possess (10[2])this (10[3])property, (10[3]-5[2])and have zero (10[1])overlap (10[1]-5[1])with ungerade (“oon-guh-RAH-duh”) orbitals that are “anti-[this (10[2])property]”. (10[2]-5[3])Molecules (-5[1])described (-5[1])by the “centro” form of this property (10[2])cannot (10[1])be both IR and (10[1])Raman active. (10[1])Chiral molecules lack (10[1])this property (10[1])since they do not have inversion (10[4])centers or mirror planes. (10[1])For 10 points, name this property that describes how compounds can appear the same after being rotated (10[1])or reflected. (10[1])■END■ (10[7]0[3])
