Sub-picosecond time resolved infrared spectroscopy of high-spin state formation in Fe(ii) spin crossover complexes.


The photoinduced low-spin (S = 0) to high-spin (S = 2) transition of the iron(ii) spin-crossover systems [Fe(btpa)](PF(6))(2) and [Fe(b(bdpa))](PF(6))(2) in solution have been studied for the first time by means of ultrafast transient infrared spectroscopy at room temperature. Negative and positive infrared difference bands between 1000 and 1065 cm(-1) that… (More)
