چکیده

The most refined nucleus-independent chemical shift index (NICS(0)(πzz)) and the extra cyclic resonance energies (ECREs), based on the block localized wave function (BLW) method, show that the aromaticity of all azines is like that of benzene. The same is true for aza-naphthalenes relative to naphthalene. The lower relative energies of isomers with vicinal N's are due to the weakness of NN bonds rather than to reduced aromaticity.

Aromaticity as the driving force for the stability of non-IPR endohedral metallofullerene Bingel-Hirsch adducts.

We have studied the relative stabilities of Bingel-Hirsch non-IPR endohedral metallofullerene monoadducts having one, two, or three adjacent pentagon pairs. The most stable addition always leads to an open adduct and never occurs on [5,5] bonds. Our results show that the thermodynamics of the addition is governed by the additive local aromaticity of the rings of the final adducts.

Didehydrophenanthrenes: structure, singlet-triplet splitting, and aromaticity.

In this work, we explore the geometries, relative stabilities, singlet-triplet (S-T) splittings, and local aromaticities of the 25 possible didehydrophenanthrenes (DDPs) at the BLYP/6-31G(d) level. The main aim is to understand their molecular structure and stability in terms of the electronic structure. To this end, we analyze the changes induced by didehydrogenation in molecular structure and...

Relative Stability and Spectroscopic Regularity of C80O Based on C80(D5d).

The relative stabilities of the nine possible isomers for C80O based on C80(D5d) were investigated via density function theory (DFT) at B3LYP/6-31G(d) level. The most stable geometry of C80O is predicted to be 23,24-C80O, where an annulene-like structure is formed. The stretching vibration frequencies of the C=C bonds in the IR spectrum of C80O compared with those of the C=C bonds in the IR spe...

DFT Study of Kinetic and Thermodynamic Parameters of Tautomerism in 4−acyl Pyrazolone

In the present work, DFT calculations are employed to obtain the optimized structures of 4- acyl pyrazolone tautomers (19 tautomers) using B3LYP/6-311++G** calculations. In addition, molecular parameters, IR frequencies and relative energies are extracted for all tautomers. The existence of aromatic ring, keto tautomer (versus enol tautomer), N-H bond (versus C-H bond) and C=N double bond (vers...
