Definition of Tautomerism

Tautomerism
Tautomerism Tau*tom"er*ism, n. [Gr. ?; ?, for ? ? the same + ? part.] (Chem.) The condition, quality, or relation of metameric substances, or their respective derivatives, which are more or less interchangeable, according as one form or the other is the more stable. It is a special case of metamerism; thus, the lactam and the lactim compounds exhibit tautomerism.
