Abstract:

Using information derived from a combination of effusion and mass spectrometric techniques, the dissociation energy of Co2 has been calculated from the ratio of dimeric and monomeric cobalt in equilibrium with the liquid as dissociation energy Co2 30 6 kcal. Upper limits to the dissociation energy of Ti2, Cr2, and Mn2 are also estimated as dissociation energy Ti2 58 kcal dissociation energy Cr2 44 kcal dissociation energy Mn2 21 kcal. These results are correlated with the energy required to promote the atom to the lowest lying bonding or valence state of electron configuration 3d to the n-1 power 4s. Author
