[f. electro- + -meric as in isomeric a.]

1923G. N. Lewis Valence xi. 132 We no longer..see any justification for the assumption that nitrogen trichloride must be either N+++Cl3-, or N---Cl3+. Such a pair of hypothetical substances have become known in the modern dualistic theory as electromers. Ibid., It is hardly to be expected that we shall be able to segregate and isolate the several species of molecules so as to obtain electromeric substances. 1941Nature 28 June 813/2 The effect depends on the possibility of the electromeric displacement..in the transition state. 1964N. G. Clark Mod. Org. Chem. xxv. 529 This temporary electronic displacement is known as the electromeric effect, and it operates in the same sense as the mesomeric effect. |
