An energetic material, nitratoethylnitramine (NENA), its tautomers and also its charged forms are considered quantum chemically, using various basis sets at the levels of ab initio and density functional theories (DFT). NENA has been found to be sensitive to negative charge development, resulting in rupture of O-NO(2) bond. Also conformational and molecular dynamics (MD) studies have been performed on NENA. Various geometrical parameters, energies and infrared spectra have been obtained and discussed. Also, calculations indicate that s-cis conformation of NENA is slightly more stable than the s-trans and the tautomers of it have very comparable total energy values to NENA. On the other hand, on the basis of homolytic bond dissociation energies (BDE) for O-NO(2) bond in the structures, it is clear that the presence of the tautomers in the bulk of NENA somewhat should decrease its sensitivity.

Quantum chemical calculations of warfarin sodium, warfarin and its metabolites Tekin, Emine Deniz (Calisir); ERKOÇ, Figen; YILDIZ, İLKAY; Erkoç, Şakir (2008-07-01) The structural, vibrational and electronic properties of warfarin sodium, warfarin and its metabolites have been investigated theoretically by performing the molecular mechanics (MM+ force field), the semi-empirical self-consistent-field molecular-orbital (AM1), and density functional theory calculations. The geometry of the molecules have been optimized, the vibrational dynamics and the electronic properties of the molecules have been calculated in their ground state in gas phase.
Structural and electronic properties of InmSen microclusters: density functional theory calculations Erkoc, S; Katırcıoğlu, Şenay; Yilmaz, T (2001-06-15) We have investigated the structural and electronic properties of isolated InmSen microclusters for m + n less than or equal to 4 by performing density functional theory calculations. We have obtained the optimum geometries, possible dissociation channels and the electronic structure of the clusters considered.
Investigation of ruthenium-copper bimetallic catalysts for direct epoxidation of propylene: A DFT study Kizilkaya, Ali Can; Senkan, Selim; Önal, Işık (2010-09-01) Propylene epoxidation reactions are carried out on Ru-Cu(1 1 1) and Cu(1 1 1) surfaces with periodic density functional theory (DFT) calculations. Ru-Cu(1 1 1) surface is modeled as Cu(1 1 1) monolayer totally covering the Ru(0 0 0 1) surface underneath, in accordance with the literature. It is shown that the Ru-Cu(1 1 1) surface is ineffective for propylene oxide formation since it has a lower energy barrier (0.48 eV) for the stripping of the allylic hydrogen of propylene and a higher energy barrier (0.92 ...
Anisotropic Elastic and Lattice Dynamical Properties of Cr2AB MAX Phases Compounds Gencer, Ayşenur; Yılmaz, İnanç; Bayhan, Ülkü; Sürücü, Gökhan (2019-03-01) The structural, mechanical and lattice dynamical properties of the MAX Phase borides compounds Cr2AB (A= Al, P, Si) have been investigated using the first principles calculations with the generalized gradient approximation (GGA) based on Density Functional Theory (DFT). The obtained negative formation energies of Cr2AB indicate that these compounds are stable and could be synthesized. Some basic physical parameters such as lattice constants, elastic constants, bulk modulus, Shear modulus, Young’s modulus, a...
Density functional theory calculations of small ZnmSn clusters Katırcıoğlu, Şenay (2001-07-16) We have investigated the structural and electronic properties of isolated neutral ZnmSn clusters for m + n less than or equal to 4 by performing density functional theory calculations at B3LYP level. We have obtained the optimum geometries, the electronic structures, and the possible dissociation channels of the clusters considered.
