Good Agreement

A variation of the temperature changes the static dielectric constant (ε) and the refractive index (n) of solvents and, in conjunction with the measurement of solvent shifts of absorption and fluorescence maxima, allows the investigation of dipole moment changes of solutes in the excited state. For this purpose, investigations of the temperature dependences of ε and n of some pure and mixed solvents of different polarities have been made. It is found that the excited dipole moments of indole, 1,2-dimethylindole, 2,3-dimethylindole and tryptophan obtained from the shifts of the fluorescence maxima in mixed solvents at high temperatures are in good agreement with those obtained in other ways.

This work focuses on the spectroscopic study of RE3+ ion, namely, trivalent neodymium (Nd3+) doped lead borotellurite glass with a composition of TeO2-B2O3-PbO. The glass sample has been prepared by conventional melt-quenching technique. The density, molar volume and optical energy band gap of these glasses have been measured. The refractive index, molar refraction and polarizability of oxide ion have been calculated by using Lorentz-Lorentz relations. The absorption spectra are recorded using UV-Vis-NIR spectrometer in the range of 200-900 nm.
