Show affiliationsAdsorption of the first-row transition 3d metals (Ti-Cu) on the atomically clean Mo(110) surface in ultra-high-vacuum conditions has been studied by Auger electron spectroscopy and work function measurements (Anderson method). In this letter it is shown that adsorption behaviour of the metals under consideration systematically changes along the 3d series. The observed correlation between the systematic change of the dipole moments and the values of the charge transfer from adatom to substrate along the period leads us to the conclusion that the metal 3d orbitals play an important role in the formation of the chemisorption bond.
