Structural and spectroscopic characterization of an einsteinium complex.
Photophysical measurements show antenna sensitization of EsIII luminescence and a hypsochromic shift on metal complexation, which had not previously been observed in lower-atomic-number actinide elements, indicative of an intermediate spin-orbit coupling scheme in which j-j coupling prevails over Russell-Saunders coupling.
