The vibrational relaxation involves at least two modes: the FeN stretching mode (see picture) and the coherently excited chelate-ring and bending mode, which relax on different time scales.ironspin crossovertime-resolved spectroscopyultrafast dynamicsvibrational relaxationRaman-SpectroscopyDft CalculationsCrossoverComplexesIron(Ii)DynamicsSpectraVibrational coherences and relaxation in the high-spin state of aqueous [Fell(bpy)3]2+text::journal::journal article::research article
