He I photoelectron spectra are reported for the metallocene species (C5H5)2V, (C5H5)2Cr, (C5H5)2Mn, (C5H5)2Co and (C5H5)2Ni, and for their 1,1′-dimethyl derivatives. The metal 3d ionisation structure is discussed in terms of ligand field theory. The unusual spectrum of (C5H4Me)2 Mn is interpreted in terms of a high-spin/low-spin equilibrium in the gas phase.
