High spin und low spin komplexe
WebMar 4, 2013 · In this screencast, Andrew Burrows walks you through the use of magnetic data to determine whether a complex is high spin or low spin. http://ukcatalogue.oup... WebSpin crossover (SCO) is a phenomenon that occurs in some metal complexes wherein the spin state of the complex changes due to an external stimulus. The stimuli can include temperature or pressure. Spin crossover is sometimes referred to as spin transition or spin equilibrium behavior. The change in spin state usually involves interchange of low spin …
