in this paper geometry optimization of two ionic complexes such as cr042-gly+1, and mo042- gly+i have been carried out at the hf and b3lyp levels oftheory with 6-31g* basis set in the gas phase. moreover, chemical shift andnatural bond of orbital (nbo) of these compounds have been obtainedusing nmr and nbo methods. finally, the obtained theoretical results werecompared with each other.
A novel phenoxo-bridged zinc complex, [Zn2(L)µ(O-O)2H2OCl2] [L= deprotonated salen ligand, 2,2?-((1E,1?E)-((2,2-dimethylpropane-1,3-diyl)bis(azaneylylidene))bis(methaneylylidene))diphenol), was reported. The title complex characterized by elemental analyses, single crystal X-ray crystallography, spectroscopic studies, and thermogravimetric analysis. structure analysis reveals the coordination o...
در این تحقیق، عکس العمل نانو لوله های تک دیواره کربنی و بور نیترید به کرنش و همچنین رفتار صفحه های گرافنی و بور نیترید هگزاگونال در برابر لوله کردن در سطح b3lyp/6-31g مورد بررسی قرار گرفته است. آروماتیسیته حلقه های شش تایی در نانو لوله های کربنی و بور نیترید تک دیواره و همچنین صفحه های گرافنی و بور نیترید هگزاگونال توسط کمیت جابجایی شیمیایی مستقل از هسته (nics) در مرکز حلقه های مختلف در طول کرن...
Two very different quantum mechanically based energy decomposition analyses (EDA) schemes are employed to study the dominant energy differences between the eclipsed and staggered ferrocene conformers. One is the extended transition state (ETS) based on the Amsterdam Density Functional (ADF) package and the other is natural EDA (NEDA) based in the General Atomic and Molecular Electronic Structur...
This work reports a systematical study highlighting the impact of substrate induced stress as key parameter for electrical performance and phase transition temperatures (K,Na)NbO 3 polycrystalline thin films.
N–((2–Acetylphenyl)carbamothioyl)benzamide has been synthesized and characterized. The molecular conformation of the investigated compound is stabilized by C16–H16B⋅⋅⋅O2i (i: 1+x, y, z) intermolecular C14–H14⋅⋅⋅S1, N2–H2⋅⋅⋅O2, N2–H2⋅⋅⋅O1 intramolecular H–bonds. All DFT calculations have implemented at B3LYP level with 6–311G(d,p) basis set. optimized structure parameters compared experimental o...

محاسبات از اساس بر روی کمپلکس های mim-bf4در فاز گازی، با استفاده از روش های dft(b3lyp)و mp2 با مجموعه پایه های 6-311++g(2d,2p)، 6-311++g(2df,2pd)، 6-311++g(3df,2pd)، aug-cc-pvdz و aug-cc-pvtz انجام شده است. ما چهار کمپلکس برروی سطوح انرژی پتانسیل بر همکنش بین bf4وmim یافته ایم. تحلیل اوربیتال پیوند طبیعی(nbo) و نظریه اتم در مولکول (aim) برای ارزیابی ماهیت برهمکنش ها در کمپلکس های mim-bf4 استفاد...
In this paper, is calculated structural optimization and interactions on surface nanotubes (AlN,CNT) and phosgene. Based on the optimized ground state geometries using B3LYP/6-31G* method, the NBO analysis of donor-acceptor (bondanti bond) interactions revealed that the stabilizationenergies associated with the electronic delocalization.
