WebAug 17, 1998 · The optical basicity Λ of the oxides has been estimated on the basis of average electronic oxide polarizability calculated from the refractive index Λ(n 0) and the energy gap Λ(E g). A good agreement has been observed between the optical basicity data obtained using independent initial quantities. WebThe optical basicity of complex nitrides can therefore be calculated by the same method established for oxides using the equivalent fractions and the basicity of the constituent nitrides. The relationship between nitride polarizability α N and basicity Λ(nitride) was found to be linear, with Λ(nitride) = 0.39α N − 0.14 where α N is given ...
WebSep 1, 2003 · Optical basicity of a medium is strongly influenced by the polarizing strength of the cations present. A strongly polarizing cation will attract and bind the ligands towards that cation. Such binding reduces the electron donating power of the ligands towards the probe ion resulting in smaller optical basicity.
