Faraday constant correlation

Where R is the gas constant, T is the temperature, and F is the Faraday constant. Caused by the logarithmic correlation between the gas concentration and the voltage signal, the potentiometric measurement is best suited for measurements of small amounts of oxygen. A well-known application of this principle has been realized in the so called lambda-probe for automotive applications where they are used to control the lambda value within a small interval around 1 = 1. The lambda-value is defined by the relation between the existing air/fuel ratio and the theoretical air/fuel ratio for a stoichiometric mixture composition ... 

In spite of the high ionic conductivity, there is no guarantee that the IL can transport the desired ions such as metal ions or protons. It is therefore important to analyze the ion transport properties in ILs. The ion conduction mechanism in ILs is different from that in molecular solvents. The ionic conductivity is generally coupled to carrier ion migration and ionic conductivity (a) correlates to diffusion coefficient (D) according to the Nernst-Einstein equation (see Eq. (3.10)) where n and q imply the number of carrier ions and electric charge, respectively. R, T, and F stand for the gas constant, the temperature in K, and the Faraday constant, respectively. 

Natural optical activity is based on the structure of the molecules (optically active centres). Artificial optical rotation is found in magnetic fields the Faraday-Verdet effect or Magneto-Optic Effect, discovered by Michael Faraday in 1845. The theoretical basis for this effect was developed by James Clerk Maxwell in the 1860s and 1870s. From investigations on small molecules we know that the study of magneto-optical rotation offers interesting correlations with the chemical structure and that additive properties of the Verdet constant have been found. 

The first contribution in Eq. (16) probes the uniform (q = 0) spin correlations, Xj( ) is the Faraday spin susceptibility, and C0 is a constant depending on the hyperfine parameters. The second term probes the q = 2kF contribution. The 2kF contribution can be temperature dependent or...

During the last 80 years, hundreds of papers have appeared on the attempts to analyze intermolecular forces in liquids. Entailed in these analyses are arguments carrying a bewildering variety of connotations of the terms polar, nonpolar, normal, abnormal, associated, nonassociated, physical interaction, chemical interaction, ideal, and nonideal. I need only refer to the relevant Discussions of the Faraday Society held in 1937, 1953, 1965, and 1967. Certain workers pin the distinction of polar from nonpolar to the relative magnitude of the dielectric constant. Others connect these terms with the possession or otherwise of a dipole moment. I can find no systematic correlation between solubility, expressed as a mole ratio, and the dipole moment, or dielectric constant.
