Vibrational assignment of dibenzoylmethane. A density functional theoretical study
Molecular structure and vibrational frequencies of 1,3-diphenyl-1,3-propanedione, known as dibenzoylmethane (DBM), have been investigated by means of density functional theory (DFT) calculations. The results were compared ...
Conformational stability, molecular structure, and intramolecular hydrogen bonding of thenoyltrifluo
Complete conformational analysis of all possible keto and enol forms of thenoyltrifluoroacetone
(TTFA) was carried out using density functional theory with the B3LYP
functional and the 6-31G**, 6-311G**, and ...
Molecular structure and vibrational assignment of dimethyl oxaloacetate
A complete conformational analysis of the keto and chelated enol forms of dimethyl oxaloacetate (DMOA), a b-dicarbonyl compound,
was carried out by ab initio calculations, at the density functional theory (DFT) ...
Theoretical study of intramolecular hydrogen bonding in the halo derivatives of 1-amino-3-imino-prop-1-ene
Intramolecular hydrogen bonding (IHB) of 1-amino-3-imino-prop-1-ene (AIP), as the simplest
resonance-assisted hydrogen bond system in symmetric N–H· · ·N class, and its halo derivatives (F, Cl, and
Br) have ...
Theoretical and spectroscopic studies on molecular structure and hydrogen bonding of 2-trifluoroacetylphenol
The molecular structure, intramolecular hydrogen bonding, and vibrational frequencies of 2-trifluoroacetylphenol (TFAP), were investigated by means of density functional theory (DFT) calculations and NMR, IR, and Raman ...
