Investigating the role of valence electrons in the magnetism of molecular crystals

Using synchrotron infrared light and near-infrared/visible laser without applying a magnetic field, we observed the response of valence electrons in the (C₂H₅)(CH₃)₃As(Pd(C₃S₅)₂)₂ crystal. The results revealed that about half of the valence electrons contribute to antiferromagnetism, while the other half form weak pairs associated with charge ordering and lattice distortion. By comparing the valence electron configurations identified in this study…
