enol

 [e´nol]
an organic compound in which one carbon of a double-bonded pair is also attached to a hydroxyl group, thus a tautomer of the ketone form. The term is also used as a prefix or infix, often italicized.

e·nol

(ē'nol),
A compound possessing a hydroxyl group (alcohol) attached to a doubly bonded (ethylenic) carbon atom (-CH=CH(OH)-); properly italicized when attached as a prefix or infix to an otherwise complete name, for example, enolpyruvate, phosphoenolpyruvate; usually in equilibrium with its keto tautomer.
[-ene + -ol]

enol

(e´nol) an organic compound in which one carbon of a double-bonded pair is also attached to a hydroxyl group, thus a tautomer of the ketone form; also used as a prefix or infix, often italicized.

enol

[ē′nol]
an organic compound with an alcohol or hydroxyl group directly attached (bonded) to a double bond. By transfer of the hydrogen atom from oxygen to carbon, the enol form becomes the (usually more stable) keto form. Such compounds usually exist as enol-keto tautomers.

e·nol

(ē'nol)
A compound possessing a hydroxyl group (alcohol) attached to a doubly bonded (ethylenic) carbon atom (-CH=CH(OH)-).
[-ene + -ol]

enol

one of two tautomeric forms of a substance, the other being the keto form; the enol is formed from the keto by migration of hydrogen from the adjacent carbon atom to the carbonyl group.

Hence, the first emission band observed at 385 nm (COP-UAN) and 391 nm (UAN) can be interpreted in terms of the direct emission from the intramolecularly H-bonded enol form, whereas the emission with higher intensity (480 nm and 520 nm, respectively,) can be assigned to the "de-excitation" process from the keto form of urethane anil structure appeared through tautomerization process.
