The resonance Raman spectra of potassium μ‐oxobis[pentacyanomanganate(III)] cyanide, K 7 [Mn 2 O(CN) 10 ]CN, were measured using exciting lines at 356.4, 406.7, 530.9, 568.2, 603.5, 647.1 and 676.4 nm. By combining these data with those obtained previously (excitations at 457.9, 476.5, 488.0, 496.5, 514.5 and 608.6 nm), the excitation profiles were plotted for three totally symmetric vibrations at 1880 (CN ax strech), 527 (MnC ax stretch) and 259 cm −1 (MnOMn stretch). It was found that the equation derived by Mingardi et al. can adequately express these excitation profiles and that the previous assignment of the electronic transition at 509 nm needs revision.
