We report vibrational Raman and infrared spectra for chemically separated CbO and C7e fullerenes. Thin film samples were prepared by subliming the chromatographically separated species onto appropriate substrates. The Cso Raman spectrum shows eight clear lines and two weaker ones. If CsO in fact has

The triplet state Raman spectra of C6O and C7o in toluene were obtained using the pump/probe technique. For C6o, new bands at 1461 and 1475 cm-1 appeared around 1470 cm-1 in the triplet state. The Raman peaks at 1448 and 1368 cm-1 for C7o shifted to lower frequencies due to the increase in antibondi
Resonant electron capture by C 60 and C 70 was studied and it was established that long-lived (i.e. mass spectrometrically observable) parent negative ions are formed within an extremely broad energy region (0-14 eV). It has been shown that effective yield curves of C 60 -and C 70 -in the thermal en
Photophysical properties of the singlet and triplet states of the fullerenes, &,, and CrO, have been investigated in toluene, benzene, hexane and ethanol solutions by pica-and nano-second laser flash photolysis techniques. Lifetimes, extinction coefficients, quantum efficiencies of the formation of
