 Abstract    l e c t r o n i c R a m a n S p e c tr a o f a L o w -S p in F e r a P o r p h y r i n a n d R e e x a m in a tio n o f th e V ib r a t i o n a l S p e c tr a o f K 3[F e (C N)6] a n d [F e (C 5H 5)2]B F4 The resonance Raman spectra of (nBu4N)[Fe(CN)2TPP] (("BiitN): tetra(n-butyl)ammonium; TPP: m-tetraphenylporphyrin), K3 [Fe(CN)6] and [Fe(C5H5)2]BF4 have been investigated. A molec­ ular electronic Raman (ER) effect at 545 cm"1 is observed for (nBu4N)[Fe(CN)2TPP]. The transi­ tion occurs between lower 'TV' and upper 'Tg" level of the spin-orbit split ground state assuming pseudo-octahedral symmetry. In contrast to earlier studies no ER effect is detected for K3[Fe(CN)6] and [Fe(C5H5)2]BF4. For Raman shifts < 800 cm-1 only one strong Raman line is observed for [Fe(C5H5)2]BF4 at 311 cm-1, assigned to the iron ring stretch designated by u4 (aig in D5(j). Due to a phase transition of K3[Fe(CN)6], two additional strong vibrational lines at 329 and 352 cm-1 appear in the Raman spectrum taken at 10 K. Their intensities show A "term" behaviour of the resonance Raman effect with overtones and combinations for both lines. These are components of the vibronic combinations with the i/6, vi, and i/g modes (tiu in Oh) in the IR spectra, too.
