Abstract:	The UV photoelectron spectra of a series of aromatic mercury derivatives {(C₆H₅)₂ Hg, (pCH₃C₆H₄)₂Hg, C₆H₅HgCl, pCH₃C₆H₄HgCl} and of a series of alkynyl mercury derivatives {(CH₃C)₂Hg, ((CCH₃)₃CCC)₂Hg, (ClCC)₂Hg} are reported and discussed. Particular attention is devoted to possible interactions between mercury orbitals and π systems of the ligands. In this respect differences are observed between the two series: in the alkynyl derivatives ligand-field effects are evident on the 5d mercury orbitals, whilst they are not observable in the aromatic compounds.
