To rectify this, he proposes a better set of terms for understanding mathematical stereochemistry and new approaches, and he discusses the classification of isomers, point-group symmetry, sphericities of orbits and prochirality, the foundations of enumeration under point groups, symmetry-itemized enumeration and gross enumeration under point groups, enumeration of alkanes as 3D structures, permutation-group symmetry, stereoisograms and RS-stereoisomers, stereoisograms for tetrahedral derivatives and allene derivatives, stereochemical nomenclature, pro-RS-stereogenicity based on orbits.
While the government took some tangible steps to raise awareness of human trafficking, including the establishment of focal point groups and an anti-trafficking task force, some local observers felt that the government discouraged discussions on developing effective strategies for combating this phenomenon of modern-day slavery.
Two model examples--hexamethylbenzene, a centrosymmetric crystal with both covalent and Van der Waals bonds, and anhydrous alum, a nocentrosymmetric structure typical of ceramics and metals--are chosen as model crystals and used to explain symmetry, point groups, space groups, Bravais lattices, reciprocal lattices, and diffraction maxima.
