The property of a chemical compound to exist in or shift between two or more distinct molecular forms with different arrangements of atoms.
From Greek 'desmos' (bond) and 'tropos' (turning) plus the suffix '-ism' indicating a property or condition. A chemistry term coined to describe molecular shape-shifting.
