WebNov 30, 2024 · modifier. The molar polarizability, αm, oxide ion polarizability, αo2-and optical basicity, Λ of the glasses are calculated by Lorentz-Lorenz equation. The glasses were found to possess αm values 3, and αo2-values between 3.303 to 4.772. Meanwhile, optical basicity increases from 0.115 to 0.893. Keywords: barium oxide, refractive index ...
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. 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 ...
