Abstract
A comprehensive Raman spectroscopic study of the acetates of potassium, sodium and magnesium in the solid state have been made at both 298 and 77K. Band separation of the CO stretching region was not achieved in the 298K spectra but was in the 77K spectra. The CO stretching vibration is observed as a single band in both the 298 and 77K spectra and its frequency is cation dependent. Single C–C stretching bands are observed for the acetates in the 77K spectra. The OCO deformation vibrations were also cation dependent. Low frequency vibrations of magnesium acetate are observed at 338, 253 and 268cm−1 and are assigned to the MgO stretching vibration of the magnesium bisacetato complex. Low frequency bands were also observed for sodium acetate at 219, 277 and 288cm−1.
