Refractive indices of solvents

Xq is the wavelength of the incident radiation in vacuum o is the refractive index of solvent at this wavelength Aa is the Avogadro s number... 

The microform effect can be utilized to evaluate the equilibrium chain rigidity on the basis of dynamo-optical data alone without using hydrodynamic data. Thus the dependence of [n]/[ij] on the refractive index of solvent for various cellulose ether and ester elutions has been studied (Fig. 30) ...

Fig. 7.12. Two tubes containing Pyrex beads in glass wool and solvent (a) the refractive index of solvent matches that of glass wool and (b) the refractive index of solvent is different from that of glass wool or pyrex beads and scattering from the glass wool dominates.
