Structural defects named for this adjective drive the odd-even effect in short-chain self-assembled monolayers. This adjective identifies the cubic, covalent network solid allotrope of nitrogen that has the highest energy density of any compound. Pentane interference and the anomeric (“AN-oh-mair-ick”) effect are specific cases of a donor-acceptor effect named for this adjective; that effect, which maximizes hyperconjugation at any cost, is most often observed in vicinal di·fluorides. Local — but not global — energy minima occur at the two syn·clinal rotamers (“ROH-tuh-mers”) described by this adjective. This adjective identifies the steric interactions that are equivalent to cyclohexane’s 1,3-di·axial repulsion. This adjective means that two adjacent positions on a Newman diagram, separated by a 60-degree dihedral angle, are both substituted.
