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 D00(Co2)=39±6 kcal. Upper limits to the dissociation energy of Ti2, Cr2, and Mn2 are also estimated as D00(Ti2)D00(Cr2)D00(Mn2)dn—14s.
