title: "Conformational lock"via unusual intramolecular C-FO[double bond, length as m-dash]C and C-HCl-C parallel dipoles observed in in situ cryocrystallized liquids.
abstract: We report an unusual intramolecular C-FO[double bond, length as m-dash]C and C-HCl-C parallel dipole-dipole alignment which "locks" the molecular conformation of cryocrystallized liquids towards planarity where the diatropic ring current establishes the existence of aromaticity in the five-membered ring associated with FO contact. Topological analysis establishes the bonding interaction between [F, O] and [H, Cl].
