Paper Abstract

Polycrystaline silicates IR and Raman spectra in the range of internal complex anion vibrations are due to crystal field splitting and Davydov's effect are complicated and therefore, correct bands assignement is fundamental problem. The 28Si - 30Si isotopic effect observation is very helpful for better spectra understanding. Because of FT-IR spectroscopy advantages, the accuracy of isotopic bands shift measurements is satisfactory even for small (ca. 6% ) silicon isotopes mass difference. Based on isotopic data, the force constants calculations with molecular approximation for silicates complex anion has been performed.
