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...
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...
that promise exponentially faster calculations, become more mature every year. The question that has emerged is how to map existing chemistry problems, such as excited state calculations, to this new type of computing hardware. Whereas a solution has already been found for the gate-based quantum c...
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.

1-Eim protons share more electron densities than water protons via the H-bonds, which are stronger between dissimilar molecules than between similar ones. The stable H-bonded structure of water molecules breaks when x is about 0.1, while the stable H-bonded structure of 1-Eim molecules forms ...
The resulting optimization algorithms will enable other scientists to semi-automatically construct multi-protein structures that match negative stain electron microscopy images. Collaborators’ projects have so far involved hand-placed molecules of density sufficiently small to be understood when all of them...
The frontier molecular orbital behavior of the individual molecules and their complexes can be defined qualitatively through the electronic distribution models. The HOMO-LUMO orbitals of the GO, NIPAM, and GO/NIPAM are shown in Fig.2. For the GO surface, the electron moiety of the HOMO spreads...
(Fig.1aand inset of Fig.4a), an electron was used as a probe particle. For attachment energy maps (AEMs), molecules were used as probes. High-resolution AEMs were used to optimise the crystal structure determined by STM for subsequent simulations. These optimised geometries are in good ...
