| dc.description.abstractEn | We report on the light induced spin crossover dynamics of [Fe(phen)<sub>3</sub>] (BF<sub>4</sub>)<sub>2</sub> (phen = 1,10-phenantroline) complex dissolved in acetonitrile. This complex was excited by picosecond and femtosecond laser pulses whose central frequency was centered on the <sup>1</sup>A<sub>1</sub> → <sup>1</sup>MLCT optical transition. Our analysis that well reproduces the recorded transient absorptions suggests this complex relaxes following inter-system crossing cascade: <sup>1</sup>MLCT(<i>S</i> = 0) → <sup>3</sup>MLCT(<i>S</i> = 1) → <sup>5</sup>T<sub>2</sub>(<i>S</i> = 2) → <sup>1</sup>A<sub>1</sub>(<i>S</i> = 0). The <sup>3</sup>MLCT and <sup>5</sup>T<sub>2</sub> states were identified, thanks to the triplet-triplet <sup>3</sup>MLCT → <sup>3</sup>MLCT<sup>∗</sup> and <sup>5</sup>T<sub>2</sub> → <sup>5</sup>MLCT optical transitions. Our experiments well agree with the relaxation mechanism recently proposed and clearly indicate the impact of the solvent on the measured relaxation constant time. | |
