Webare collectively described as either the Polyhedral Skeletal Electron Pair Theory (ref. 19) or Wade's Rules. The ideas have proved to be surprisingly useful for analysing the structures of a wide range of polyhedral molecules, however by their very simplicity there are a number of notable exceptions to the theory. These exceptions can be WebIn chemistry the polyhedral skeletal electron pair theory (PSEPT) provides electron counting rules useful for predicting the structures of clusters such as borane and carborane …
WebJan 19, 2012 · The polyhedral structures of these isomers have more than one open side (i.e., two or more nontriangular faces). Hence they have arachno-like structures, although they have only n + 1 (n = 7) electron pairs: again the PSEPT rules are violated.All of these structures are characterized by the locations of two bridged bonds; one is at the same … WebIn the electronic and torsional and rotational ground state of toluene, the strengths of the diatropic and paratropic nuclear… Show more We develop the theory of nuclear ring currents induced by external magnetic fields in torsional molecules. The theory is applied to toluene, whose torsion axis is oriented along the magnetic field.
