Identification and atomization energies of gaseous LaC7 and LaC8 by high-temperature mass spectrometry
Abstract
The atomization energies, D°0, and standard heats of formation, ΔHf, 298.15, in kJ mol–1, of the new molecules LaC7 and LaC8 have been obtained from Knudsen effusion mass-spectrometric measurements as 4320 ± 60 and 1095 ± 50 for LaC7(g) and 4992 ± 70 and 1140 ± 60 for LaC8(g).
