Abstract :
We have measured the evolution of the THz spectrum of polymeric iron(II) spin crossover compounds within the Low-Spin/High-Spin thermal hysteresis loop in the ~0.6-6 THz frequency range. This study enabled to evidence the large variations of both the refractive optical index and the absorption that occur during the spin state phase transition.
