Mass spectrometric determination of the dissociation energies of the gaseous rare earth monoselenides and monotellurides

Abstract

The dissociation energies of the following gaseous monoselenides and tellurides were determined: [graphic ommitted] The dissociation energies of the remaining rare earth chalcogenides, Yb excepted, were estimated by comparison with the oxides and sulphides. They are: [graphic ommitted].
