Density functional theory of atoms and molecules Robert G. Parr, Yang Weitao
Publisher: Oxford University Press, USA

In theoretical chemistry, chemist and physicist are together in developing algorithms and computer program to make it possible for prediction of atomic and molecular properties and or reaction path for chemical reaction and also the simulation of macromolecular system. Journal of Atomic and Molecular Physics Furthermore, a detailed DFT calculation on the molecular structure, molecular constants, and internal rotation parameters are reported and compared with the experimental values. Fifth, a DFT study on the potential application of a prototype ZnO (6,0) zigzag SWNT as gas sensor for H 2, O2, CO, NH3 and NO2 shows that the electron-donor molecules (CO and NH3) tend to enhance the concentration of major carriers ( electrons), whereas the electron-acceptor molecules (O 2 and NO2) tend to reduce the concentration. Abs Initio methods type that are popular are: Hartree-Fock, Perturbation theory, Møller-Plesset, configuration interaction, coupled cluster, reducted matrix density and density function theory. O2 and NO2 can dissociate at the oxygen vacancy (VO) sites through filling the VO with one atomic O originated from the adsorbates.

For example, how does the behavior of water molecules and sulfur oxide impact the creation of acid rain? Molecules-logo DFT calculations show that the oxygen atom exchange arises as a consequence of the [1,3]-sigmatropic shift of iodine. A comparison of the values of J to highest occupied molecular orbital (HOMO) levels determined by density functional theory (DFT) calculations revealed an odd−even effect for the phenyl-terminated SAMs but not the pyridyl-terminated SAMs. Molecules, an international, peer-reviewed Open Access journal. The DFT models are used to understand how changes at the atomic and molecular levels influence behaviors we can see and touch.
