Abstract The Raman spectrum of solid [Fe(Sac) 2 (H 2 O 4 )] · 2H 2 O was recorded and assigned. Some comparisons with the spectra of the related copper(II) and nickel(II) complexes were also made. The excitation profiles of the vibrational modes that show pre‐resonance on excitation with laser lines within the electronic bands are reported. On this basis, and with the aid of a semi‐empirical extended Hückel MO calculation, the assignment of the metal—ligand vibrations and the interpretation of the electronic spectrum could be reinforced.
