Résumé : The monoborides and monosilicides of some transition metals have been detected in the vapours effusing from a Knudsen cell at high temperatures. Their dissociation energies have been determined to be: D0°(RuB(g))= 443.2±21; kJ/mol; D0°(RuSi(g))=393.3±21; kJ/mol; D0°(RhB(g))=472.1±21; kJ/mol; D0°(RhSi(g))= 391±18; kJ/mol; D0°(PdB(g))=325.3±21; kJ/mol; D0°(PdSi(g))=309.6±14; kJ/mol; D0°(Irb(g))= 508.5±17; kJ/mol; D0°(IrSi(g))=459.1±21; kJ/mol; D0°(AuB(g))=337.8±16; kJ/mol; D0°(PtSi(g))= 497.3±18; kJ/mol; D0°(AuSi(g))=307.8±12; kJ/mol. D0°(AuSi(g))=307.8±12kj/mol.
