Sommaire. 2014 Dans la première partie de cet exposé nous rappelons les divers phénomènes qui produisent des particules solides de carbone et nous passons en revue les principales hypothèses qui ont été formulées pour expliquer le mécanisme de la formation de ces particules de carbone suie. Dans la deuxième partie nous présentons les observations de la molécule C3 qui ont été faites depuis l'identification de son spectre de bandes et les liens entre ces observations et la formation des particules de carbone.

The geometrical structure and the vibrational spectra of dimer Rb 2 Cl 2 , trimer Rb 3 Cl 3 , tetramer Rb 4 Cl 4 molecules and heptaatomic Rb 4 Cl 3 + , Rb 3 Cl 4 ions were studied. The cluster molecules and ions had been detected in equilibrium vapour over rubidium chloride previously. The quantum chemical calculations by DFT with hybrid functional B3P86 and MP2 methods were performed. The effective core potential with Def2-TZVP (6s4p3d) basis set for rubidium atom and full electron aug-cc-pVTZ (6s5p3d2f) basis set for chlorine atom were used. The equilibrium configuration was confirmed to be rhomb of symmetry D 2h for dimer Rb 2 Cl 2 , distorted cube (T d) for tetramer Rb 4 Cl 4 and polyhedral (C 3v) for heptaatomic ions Rb 4 Cl 3 + and Rb 3 Cl 4-. For the trimer molecule Rb 3 Cl 3 two isomers have been revealed: hexagonal (D 3h) and butterfly-shaped (C 2v), the latter has lower energy and is proved to be predominant in equilibrium vapour in a broad temperature range.

“…This latter bond length is 2.3453 A and hence the Cs-0 bond length is probably around 2.4 A 7 IP (F") is quite obviously the same as EA (F). (18,19). The (0, 8, 0) [0, 0, 0] structure for Li20 is stabilized by 9 eV relative to the Cs analog.…”
