The possible stable conformers in keto-amine or imine-enol forms of N,N'-phenylenediylbis[3-(1-aminoethyl)-6-methyl-2H-pyran-2,4(3H)-dione] on its potential energy surface (PES) were investigated by semi-empirical methods and hybrid-density functional theory (h-DFT) with the basis sets of different size and type. On account of relative energies and population analysis, the more stable forms of N,N'-phenylenediylbis[3-(1-aminoethyl)-6-methyl-2H-pyran-2,4(3H)-dione were determined %K Conformational analysis %K DFT %K PES %K N.N'-phenylenediylbis3-(1-aminoethyl)-6-methyl-2H-pyran-2.4(3H)-dione %K Tautomerism %U http://dergipark.org.tr/bseufbd/issue/41708/486208
