A study of the tautomerism of dehydroacetic acid using1H,13C (solution and CP/MAS), gated1H-decoupling techniques, deuterium-induced isotope effects on13C chemical shifts, FUCOUP and molecular modeling with AM1, has showed that this compound exists as the 3-acetyl-4-hydroxy-6-methyl-2H-pyran-2-one in solution and in the solid state. © 2000 Elsevier Science B.V.
