✦ Synopsis

Raman spectra of a number of Group I and II metal oxalates are presented. From quantitative spectroscopic studies of the pure compounds and of mixtures of calcium, potassium and magnesium oxalates, it has been demonstrated that each component can be determined in the prepared mixtures to better than 2%. Comparisons made with the Raman spectra of lithium and sodium oxalates indicate that there are characteristic differences in the observed spectra of the Group I metal oxalates and that several vibrational bands of CrO:are sensitive to the cation, being shifted to lower wavenumbers as the cation mass increases from Li to K.

The chemical structures of fresh and aged Ti-peroxy gels, made from metallic titanium and hydrogen peroxide, were analyzed in the aqueous and solid states by FT-Raman spectroscopy. Fresh transparent gels displayed strong Ti-peroxy vibrations. In gels aged for 3 years in the aqueous state the dried p
