Fourier transform infrared and FT-Raman studies on tetranuclear oxo-centered carboxylate complexes of zinc (II)

Abstract

A selection of stable Zn40(RCOO)6 complexes have been studied by FT-JR and FT-Raman spectroscopy. Polarised FT-Raman studies of two samples, which were in liquid state at ambient temperature, have also been completed. An attempt was made to construct the kinetic energy matrix for a simplified model involving 29 atoms with Td symmetry. A set of symmetry coordinates was chosen to describe the vibrational behaviour of the molecule and serve as a base for future force-field calculations. The characteristic frequencies of A1 and T2 species were assigned. Some of the E modes were also obtained.
