Determine the electron geometry and molecular geometry of BrF3. Molecular Geometry: Two atoms form a covalent bond by sharing some number of valence electron pairs. If an atom has sufficient valence electrons, then it can bond with multiple other peripheral atoms by acting as a central atom....
A survey is presented as part of an ongoing program in which the effects of electron correlation on molecular structures are studied for the purpose of obtaining data that can be used in developing force field parameters for empirical molecular modeling. In our approach, molecular structures devoid...
Electron pairs and single electron (radical) objects are rendered on your structure and automatically placed for you (you may also manually place them). Use electron pairs in conjunction with the VSEPR force field to model VSEPR shapes.
When an organic semiconductor (OS) absorbs light, electrons can be excited from the valence to the conduction band forming Coulombically bound electron-hole pairs. These excitations were described by Frenkel as energetic quasiparticles, which he named excitons1,2. Frenkel excitons as we now call th...
One of the basic conclusions on adsorption from modern surface-science studies is that bonding to surfaces is localized and takes place on specific surface ensembles and with specific geometries [93,99]. This is true even on metals, where the electron density is highly delocalized. Such ...

The highest resolution structures, with resolution values of 1 Å or so, are highly ordered and it is easy to see every atom in the electron density map. Lower resolution structures, with resolution of 3 Å or higher, show only the basic contours of the protein chain, and the atomic ...
