The Raman spectrum of Na[VO 2 Q 2 ] was recorded and assigned by comparison with related species. The excitation profiles of the vibrational modes that show pre‐resonance on excitation using laser radiation within the electronic bands are reported and three different types of profiles could be found. The electronic spectrum of the anion was also recorded and interpreted with the aid of a semi‐empirical MO calculation. This calculation, together with the results of the pre‐resonance experiments, also reinforced some of the vibrational assignments.
