โœฆ Synopsis

Ultraviolet photoelectron spectra of higher fullerenes CT8 and Cgg are measured with a synchrotron radiation light source. The spectral intensity oscillates and the peak positions shift, when the incident photon energy is changed. The hv=20 eV spectrum of CT8 resembles that of CT6, which suggests their analogous electronic structures. Comparison of the results with theoretical calculations is in favor of a C;, geometry for the main C,* isomer and a C1 geometry for C 96. Upon potassium dosing onto Cv6, a new peak emerges just above the first (HOMO) band of Cv6. The spectra are deformed at high dosage.

Ultraviolet photoelectron spectra of CT6, one of the fullerene family of compounds, have been measured with a synchroton radiation light source. The photoemission spectral onset is 1.3 eV below the Fermi level, which is equal to that of Cs4 but is about 0.5 eV smaller than that of C6c or CrO. The re

Ultraviolet photoelectron spectra of Ca4, one of the fullerene family compounds, and of potassium-dosed C84 have been measured with synchrotron radiation. The spectra of C84 are compared with those of C60 and C70. The photoemission spectral onset 0fC84 is 1.3 eV below the Fermi level, which is small

A preparative high-performance liquid chromatography was examined for the isolation of higher fullerenes from CSz extracts of the carbon soot produced by arc heating of graphite in inert atmosphere. At least eight all-carbon compounds CW, CT,,, C,,, CT8, Cs2, Csl, Cgo and Cq6 were confirmed as a "st
