desmotrope（n.）
1914, "a substance obtained from desmotropy," from desmotropy, a scientific word coined by Paul Jacobson in 1888 from Greek desmos "ligament" (see desmo-) + trepein "to turn, to change" (from PIE root *trep- "to turn"); so called "because the phenomenon is produced by a change in the linking of the atoms." [Carl Schorlemmer, "Rise and Development of Organic Chemistry," 1894]. It replaced earlier tautomerism. Related: desmotropy; desmotropic; desmotropism.
