The effect of H/D quantum nature for geometry and nuclear magnetic shielding changes are analyzed. Molecules-logo DFT calculations show that the oxygen atom exchange arises as a consequence of the [1,3]-sigmatropic shift of iodine. The molecule tetrahedrene shown below is an example of a stretched double bond that ultimately splits into a lower energy form, namely, a di-carbene. Theoretical Study of H/D Isotope Effects on Nuclear Magnetic Shieldings Using an ab initio Multi-Component Molecular Orbital Method. Examples of recent theoretical studies include computation of the structure and properties of heterocyclic carbenes using ab initio and Density Functional Methodology (DFT). Posted on May 14, 2013 by Camille. We have computed There is evidence for significant aromatic stabilization if at least two nitrogen atoms are part of the pi system in the ring. Grabowski, “Red- and Blue-Shifted Hydrogen Bonds: the Bent Rule from Quantum Theory of Atoms in Molecules Perspective,” Journal of Physical Chemistry A, vol. On a theoretical level, these properties serve as powerful descriptors for molecular modelling and design. Torre, “Domain-Averaged Fermi Hole and Domain-Restricted Reduced Density Matrices: A Critical Comparison,” International Journal of Quantum Chemistry, vol. Molecules, an international, peer-reviewed Open Access journal. Excited states can be computed within the Time-Dependent Density Functional Theory (for molecules), or within Many-Body Perturbation Theory (the GW approximation). This one-atom-thick manufacture of carbon, uniquely, as well being hidden behind the scratching of a pencil-also discovered in England for over 400 years, combines extreme mechanical strength, exceptionally high electronic and Experimental works are accompanied by theory and computational models generally based on density functional theory and/or molecular dynamics calculations, providing an important support for studying the electronic properties. O2 and NO2 can dissociate at the oxygen vacancy (VO) sites through filling the VO with one atomic O originated from the adsorbates. DFT-D and DFT-D2 energy corrections consider all pairs of atoms while DFT-D3 also consider triplets of atoms to account for three-body effects. We have theoretically analyzed the nuclear hydroxy acyl aromatic species using the gauge-including atomic orbital technique combined with our multi-component density functional theory.

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.
