VSEPR (valence shell electron pair repulsion) theory relies on the Lewis structure of molecules and polyatomic ions to predict their molecular shapes. In other words, the electron geometry of a molecule or polyatomic ion leads to the prediction of its molecular geometry....
Moreover, the stretching vibration frequencies of N-H bonds shift to lower wave number compared to the free CHZ ligand, which are caused by the delocalizations from N-H bond orbital to lone-pair electron antibond orbital of magnesium.doi:10.1007/s11595-012-0528-xXiduSchoolNieSchool聂西度...
Nuclear coupling between the halide and the Mn cluster was suggested from electron spin-echo envelope modulation of the multiline EPR signal in some Br−-substituted membrane samples (Boussac, 1995). It has been widely proposed that Cl− is directly associated with the Mn ions in the ...
Heterointerfaces between dissimilar layers of semiconductors have long been at the forefront of condensed matter physics in topics ranging from charge transfer in ap−njunction to quantum Hall effects arising in two-dimensional electron gases. For the case of complex oxide interfaces, the past decade...
The shift to higher energy on the YBCO side is consistent with the electron doping while the opposite shift on the La and Ca is due to electron depletion of the LCMO layer. The fact that Y reacts less than Ba, is potentially related to the distance from the interface and to bulk-like...

However, the arrangement of O-atoms for TlI suggests a gap or hole in the coordination geometry around this atom. This ‘hole’ is possibly occupied by a stereochemically ‘active’ electron lone pair of thallium atoms. Two hydrogen atoms of succinate situated 3.26 Å above the proposed ...
