Abstract

The problem of resolving molecular components of the electronic structure of complex, organic solids with respect to their chemical and orbital character has been approached using soft X-ray absorption (SXA) and soft X-ray emission (SXE) spectroscopy. These techniques are powerful probes of the site and angular-momentum resolved partial density of states (PDOS) for both occupied and unoccupied states. Therefore these spectroscopies are particularly suited for an analysis of the density of states of multi-atomic, complex materials as the ET-based organic conductors, allowing site-specific electronic structure to be measured. We present a preliminary picture of the electronic structure of κ-ET2Cu(SCN)2 and κ-ET2Cu[N(CN)2]Br as measured by SXE and SXA performed at the C1s and N1s core levels.
