“…77 The first four of these values are estimated from the enthalpies of formation of bulk compounds and only the latter value has been measured directly. Similar values have been obtained from calorimetry experiments: 78-85 6.3 ± 0.2 eV for Cr, 4.0-5.5 eV for Fe, 4.7-5.1 for Co, and 5.0 and 4.8 eV for Ni (111), 5.0 eV for Ni (110), and 5.4 eV for Ni (100). As a function of cluster size, vanadium behaves somewhat differently than the other metals by reaching a maximum BDE at n = 5, and then declining to a plateau above n = 10.…”
