A semi-preparative scale high-pressure liquid chromatographic method for the separation of the fullerene extract components has been developed. During the course of these separations, a new fullerene species was isolated and characterized by mass spe

X-ray and neutron-diffraction measurements have been used to study the evolution of the lattice parameter of solid C{sub 60} through the orientational-ordering transition. The lattice parameter jumps by +0.044{plus minus}0.004 A on heating, indicatin

Coherent quasielastic neutron scattering has been used to investigate the character of the rotational dynamics in the high-temperature solid phase of ${\mathrm{C}}_{60}$. The observed scattering can be described by a model in which each molecule unde

The photodissociation of copper clusters, Cu+n (n = 3–8), has been investigated in the visible region of the spectrum (710-370 nm). Photodissociation spectra have been recorded, and information on the dissociation energies obtained from measurement

The chemical reactions of size-selected Si + n ( n 2 H 4 , O 2 and D 2 O have been studied using injected ion drift tube techniques. There are large variations in the reactivity of the smaller clusters ( n + 13 and Si + 14 (and to a lesser extent Si

The chemical reactions of Si+n (n=10–65) with O2 have been investigated using selected ion drift tube techniques. The smaller clusters are etched by O2 to give Si+n−2 (and two SiO molecules) and the larger clusters chemisorb oxygen forming an Sin

The chemical reactions of Si{sub n}{sup +} (n = 11-50) with C{sub 2}H{sub 4} have been investigated at room temperature with use of injected ion drift tube techniques. The reaction kinetics for the addition of the first C{sub 2}H{sub 4} molecule have

The absorption spectrum of Cu4+ has been recorded in the visible region of the spectrum (710-370 nm) by monitoring the photodissociation of Cu4+ to give Cu3+. Ten electronic transitions have been identified, and most of them show vibrational fine str
