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. A molecule’s LCAO can be determined by applying projection operators on each stretching vector to generate “adapted linear combinations” named for this property. Molecular orbitals are described as (*) gerade (“guh-RAH-duh”) when they possess this property, and have zero overlap with ungerade (“oon-guh-RAH-duh”) orbitals that are “anti-[this (10[1])property]”. (-5[1])Molecules described by the “centro” form of this property cannot be both IR and Raman active. Chiral molecules lack this property since they do not have inversion centers or mirror planes. For 10 points, name this property that describes how compounds can appear the same after being rotated or reflected. ■END■ (0[1])
