چکیده

Trends in the chemical reactivity of transition-metal surfaces have been studied at the example of the dissociative adsorption of hydrogen on the ~100! surfaces of Rh, Pd, and Ag. Detailed calculations of the six-dimensional potential-energy surfaces have been performed using density-functional theory. The adsorption dynamics has been investigated by solving the time-independent Schrödinger equation via a coupledchannel technique. The results are discussed in the light of current concepts for a reactivity theory. @S0163-1829~99!01720-8#

AB INITIO QUANTUM CHEMICAL STUDIES IN CTAB

Quaternary ammonium compounds (QACS) are employed both as disinfectants for manual processing lines and surfaces in the food industry, and in human medicine area. QACS also cause cell death by protein denaturation . One of the QAC is cetyl trimethyl ammonium bromide (CTAB) that appears to rapture the cell membrane. The primary site of action of CTAB has been suggested to be the lipid components...

pKa predictions of some aniline derivatives by ab initio calculations

: In this work, different levels of theory containing HF, B3LYP, and MP2 with different basis sets such as 6-31G, 6-31G*, 6-311G, 6-311+G, 6-31+G*, 6-31+G are used to predict relative acidity constants of some aniline derivatives. Three different kinds of radii containing UAHF, Bondi, and Pauling are used to study how cavity forms change acidity constants. In all cases, DPCM model is used to si...

An Ab initio and chemical shielding tensors calculations for Nucleotide 5’-Monophosphates in the Gas phase

Structural and magnetic properties of purine and pyrimidine nucleotides (CMP, UMP, dTMP, AMP, GMP, IMP) were studied at different levels of ab initio molecular orbital theory. These calculations were performed at the hartree-fock level and density functional B3LYP methods. Geometries were fully optimized by following Cs symmetry restrictions. The standard 6-31G** basis set which includes polari...
