As a simple example of VSEPR theory, let us predict the structure of a gaseous BeF2molecule. The Lewis structure of BeF2(Figure 2) shows only two electron pairs around the central beryllium atom. With two bonds and no lone pairs of electrons on the central atom, the bonds are as far a...
Said three-dimensional molecular structure or molecular structure, molecular shape, molecular geometry, based on spectroscopic data on to describe three-dimensional arrangement of atoms in molecules approach. Molecular structure to a large extent affected the chemical reactivity, polarity, phase, co ...
A set of model compounds covering a range of polarity and flexibility have been simulated using GAFF, CHARMM22, OPLS and MM3 force fields to examine how well classical molecular dynamics simulations can reproduce structural and dynamic aspects of organic molecular crystals. Molecular structure, crystal...
Molecular structure-property relationships are key to molecular engineering for materials and drug discovery. The rise of deep learning offers a new viable solution to elucidate the structure-property relationships directly from chemical data. Here we show that the performance of graph convolutional networ...
By systematically altering the structure of polyemthines and squaraines, we studied the effects of molecular symmetry, strength of donor terminal groups, conjugation length of the chromophore chain, polarity of solvents, and the effects of placing bridge molecules inside the chromophore chain on the ...
