Abstract
The existence of two independent chromophores in [Ru(bipy)2(H2V)]+, where H2V− = violurate anion and bipy = 2,2′bipyridine, was demonstrated by comparing its resonance Raman spectra with those displayed by the [Ru(H2V)3]− analogue. In the former, the electronic band at 478 nm was assigned to the Ru → H2V MLCT transition, whereas the band at 415 nm was assigned to the Ru → bipy MLCT transition. In both species a tentative assignment is proposed for the enhanced modes based on comparison with related examples from the literature.Keywords
