Typical Vibrational Frequencies of Inorganic Species1
Last Update: July 26, 2005
Figure 1.2 Observed frequency ranges for polyatomic ions. See reference 2 for a description of the vibrations associated with each frequency. Raman active bands are shown as dashed lines.
Table 1. Approximate IR frequencies (in cm-1) of other common polyatomic ions not shown in Figure 1.3
Figure 2.2 Metal-ligand vibrations. See reference 1 for a complete discussion of the motions associated with each vibration. The ranges for species marked with an “*” include both bridged and non-bridged compounds. Whether a particular vibration is IR or Raman active depends on the particular geometry about the metal center.2, 4, 5, 6
