Molecular Geometry Lewis structures tell us the electron geometry of a molecule. The molecular geometry of a molecule is determined from its Lewis structure and VSEPR (valence shell electron pair repulsion) theory. The number of bonds and lone pair of electrons around the central atom of a molecu...
The dependence of the results on the choice of the basis set for sulfur (in particular the effect of incorporation of diffuses p and d orbitals) on the geometry of ligand binding, the binding energy, and the proton affinity of SH− are investigated. Comparison made with the corresponding ...
Geometry optimization and energy calculations have been performed at the density functional B3LYP/LANL2DZ level on hydrogen sulfide (HS-), dihydrogensulfide (H2S), thiomethanolate (CH3S-), thiomethanol (CH3SH), thiophenolate (C6H5S-), methoxyde (CH3O-), methanol (CH3OH), formiate (HCOO...
From the XRD data, the torsional angle of H22–N12–C11–C6 was -1.00°, and in the simulated optimized geometry, it was -0.7580° for the B3LYP. It indicates an unexpected bent conformation of the molecule, in contrary to the expected pyramidal structure. The scan was performed at a ...
