Method for determining the spin state of spin-transition compounds

摘要

The invention relates to a method for determining the spin state of a spin junction compound by irradiation with light in a defined wavelength range, detection of changes in the properties of the light caused by this interaction and correlation of these changes with the spin state of the compound, wherein as a spin junction compound a chiral transition metal complex with depending is used by the spin state variable chirooptic properties, the irradiation is carried out with polarized light and the change in the properties of the light with the chirooptic properties of the compound are correlated, characterized in that the irradiation is carried out with linearly polarized light and detects a change in the polarization direction of the light and this is correlated with the spin state of the compound.
