Fig. 3

Near- to mid-infrared spectra of the mixed-valence complexes showing the vibronic intervalence charge transfer absorption bands. a For the hydrogen bond bridged MV complexes (1a–d)+ and b for the phenylene bridged MV complexes (2b–d)+. For complexes (1a–d)+ and (2b–d)+ a symmetrical IVCT absorption band is observed. The same color code is used to show the full Gaussian-shaped IVCT band profiles for differerent MV systems with the same X substituent
