Molecular spectroscopic techniques in the characterisation and structural determination of novel systems
Molecular spectroscopic techniques in the characterisation and structural determination of novel systems
Several aspects of the use of molecular spectroscopic techniques are presented.
The use of luminescence spectroscopy as an aid to the identification of tagged polymers is presented. Inorganic phosphors have been incorporated into polymer sheets, and the resulting spectra have been analysed. The possible use of this technique in polymer recovery is discussed and the technique has been shown to be sound.
Fourier Transform Raman spectroscopy is used to examine the structure of some newly prepared brominated fullerene compounds. The spectra obtained are compared with evidence from a theoretical analysis of the compounds studied, and the two are shown to be in good agreement. The structures of the compounds under discussion are shown to be in agreement with previous postulates.
Fourier Transform Raman spectroscopy has been used to investigate the polymer - solvent interaction present in a gel containing poly (vinyl chloride) and cyclohexanone. The interaction present has been shown to be not due to hydrogen bonding interaction between the solvent carbonyl group and the hydrogen atoms present in the polymer.
An examination of the nonlinear optical properties of two polymer based composite materials is presented. A study of the effect of the poling process on nonlinear response is presented. The studies show that this class of materials is suitable for applications requiring nonlinear optical properties.

Abstract
Several aspects of the use of molecular spectroscopic techniques are presented.
The use of luminescence spectroscopy as an aid to the identification of tagged polymers is presented. Inorganic phosphors have been incorporated into polymer sheets, and the resulting spectra have been analysed. The possible use of this technique in polymer recovery is discussed and the technique has been shown to be sound.
Fourier Transform Raman spectroscopy is used to examine the structure of some newly prepared brominated fullerene compounds. The spectra obtained are compared with evidence from a theoretical analysis of the compounds studied, and the two are shown to be in good agreement. The structures of the compounds under discussion are shown to be in agreement with previous postulates.
