Abstract : Polymeric gaseous metal species of the type M sub m will increase relative to the atomic gaseous species, M, when in contact with its solid with increasing temperature if (m-1) delta H sub s greater than delta H sub m, where delta H sub s is the heat of sublimation of the solid and delta H sub m the heat of dissociation of the corresponding polymer into atoms. The heat of sublimation is greater than the dissociation energy for practically all metals where the thermal data are available and it is postulated that metal gaseous species will tend to be dimeric and polymeric at sufficiently high temperatures. The molecules Si2, Ge2, and Sn2 are probably double bonded. (Author)
