✦ Synopsis

Equilibrium mixtures of pure carbon gas-phase aggregates, C,(g), are treated combining all available observational as well as computational thermodynamical data for n = 1, 2, 3, 4, 5, 60 and 70. A considerable sensitivity to temperature and pressure is pointed out, showing that there are both regions of a higher relative population of C,(g) as well as of C,,,(g). There can be significant competition between the formation of small and large clusters. Relations between the full-equilibrium situation (i.e., including graphite), gas-phase equilibrium, and the nonequilibrium situation are discussed.

The photoluminescence (PL) spectra of C6" and CT0 in toluene, as films on silicon and as KBr pellet, were obtained as a function of temperature. Different emission profiles are observed between the fullerenes in solution and in the solid form. The PL spectra of the C&solids are similar regardless of

The energetics of the loss of C2 units from Cw and C,a has been extensively studied experimentally, but no consensus has yet been reached as to the energy of C2 dissociation from these fullerenes. We have used the Hat-tree-Fock self-consistent field theory and a hybrid of Hartree-Fock and density fu

In benzene solution, C60 and C7o interact weakly in the ground state with amines having favourable oxidation potentials. Picosecond time-resolved absorption measurements show that on photoexcilation, the weak complexes undergo charge separation to produce ion pairs which in turn undergo fast geminat

## Abstract The overall rate coefficient (__k__~1~) for the reaction of C~2~H~5~O~2~ + NO has been measured using the turbulent flow CIMS technique. The temperature dependence of the rate coefficient was investigated between 203 and 298 K. Across the temperature range, the experimentally determined
