  1 - Change of the tautomeric preference for radical cation of pyruvic acid. DFT studies in the gas phase
  Ewa Daniela Raczyńska Malgorzta Hallmann Kinga Duczmal
  Keto-enol tautomerism was investigated for ionized pyruvic acid using the DFT(B3LYP) method and the larger basis sets [6-31++G(d,p), 6-311++G(3df, 3pd) and aug-cc-pVDZ]. Change of the tautomeric preference was observed when going from the neutral to ionized tautomeric m چکیده کامل

  Keto-enol tautomerism was investigated for ionized pyruvic acid using the DFT(B3LYP) method and the larger basis sets [6-31++G(d,p), 6-311++G(3df, 3pd) and aug-cc-pVDZ]. Change of the tautomeric preference was observed when going from the neutral to ionized tautomeric mixture. Ionization favors the enolization process (ketoenol) of pyruvic acid, whereas the ketonization (ketoenol) is preferred for the neutral system. Ionization influences also -electron delocalization, which increases exceptionally in the enol form, and slightly decreases in the keto form. پرونده مقاله
