Abstract
A comprehensive analysis of the vibrational spectra (i.r. and Raman) suggests Fermi resonance interactions between fundamental modes of the acetate group and two-phonon modes associated with water in the tetrahydrates of Mg, Co and Ni acetates. The interaction is confirmed through the variations in positions and intensity ratios of the concerned bands with temperature and isotopic dilutions. It is found that the Fermi interaction constant is almost the same in all these compounds and is unaffected by lowering the temperature.
