Brief information about nanoparticles and size dependency of their properties is given. Structural properties of copper nanoparticles, Cu-n (n = 50, 100, 150) have been investigated by a modified version of diffusion Monte Carlo method, using an empirical pair potential developed and parameterized for copper. Radial distribution of atoms and the coordination numbers are investigated by the optimum geometries obtained. It has been found that stable structures of copper nanoparticles considered have compact spherical shapes.

Structural and electronic properties of dipropyl sulfide: A theoretical investigation Calisir, Emine Deniz; Erkoç, Şakir (World Scientific Pub Co Pte Lt, 2006-08-01) The structural, vibrational, electronic and QSAR properties of the dipropyl sulfide (DPS) molecule in gas phase have been investigated theoretically by performing semi-empirical molecular orbital (AM1 and PM3), ab initio (RHF) and density functional theory calculations. The geometry of the molecule has been optimized, infrared spectrum (vibrational modes and intensities) and the electronic properties of the molecule have been calculated in its ground state. It has been found that DPS molecule kinetically ma...
Structural and electronic properties of AlP doped Huckel type cyclacene with four benzenoid rings Erkoc, S; Malcıoğlu, Osman Barış (World Scientific Pub Co Pte Lt, 2003-11-01) Cyclacene of the Huckel type having four benzenoid rings have been subjected to centric perturbations along both peripheral circuits such that Al and P atoms are alternatingly located. The present structure of perturbed cyclacene let two types of isomeric compounds to arise such that in one case the peri-positions and fusion-points occupied by Al and P atoms, respectively and in the other case reversal of occupation of locations occur. For these structures, AM1-RHF type semi-empirical calculations have been...
Structural features and energetics of ZnkCdl microclusters Amirouche, Lynda; Erkoç, Şakir (World Scientific Pub Co Pte Lt, 2003-09-01) An empirical many-body potential energy function has been developed to investigate the structural features and energetics of ZnkCdl (k + 1 = 3, 4) microclusters. The most stable structures were found to be triangular for the three-atom clusters and tetrahedral for the four-atom clusters. The present results are in good agreement with available literature values.
Structural and electronic properties of the DPPC molecule Erkoç, Şakir; Korkmaz, Filiz (World Scientific Pub Co Pte Lt, 2006-07-01) The structural and electronic properties of the DPPC molecule have been investigated theoretically by performing semi-empirical self-consistent-field molecular-orbital theory calculations at the PM3 level in its ground state.
Structural and electronic properties of (CnLi)(+) cluster ions Yazgan, E; Erkoc, A (World Scientific Pub Co Pte Lt, 2005-02-01) The structural and electronic properties of (CnLi)(+) cluster ions with n = 1-6 and n = 20 have been investigated by performing density functional theory calculations at B3LYP level. The vibrational frequencies of the clusters are also calculated.
