abstract Thermal destruction of giant polyoxometalate (POM) high-symmetry nanoclusters (toroidal Mo-138 and Keplerates Mo-132 and Mo-72 Fe-30 ) was in situ investigated by Raman and IR spectroscopy. The key spectral features of POM integrity and destruction products were determined. Polarization Raman measurements of Keplerate nanoclusters carried out for the first time allowed us to determine the full set of totally symmetric modes and improve the attribution of spectral bands. The obtained results are general for all types of POMs and can be used to control the POM's integrity during the synthesis of new nanoclusters' based hybrid materials.
