Fig. 2. Comparison of the Raman spectra of [NMe₄][F(ClF)₃] (bottom, solid line) and [NPr₃Me][Cl₇] (top, solid line) with their computed spectra obtained at the B3LYP level (dashed line: solid-state calculation, dotted line: gas-phase calculation). The decomposition product [Cl₃]⁻ is marked by an asterisk.
