✦ Synopsis

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 proposed buckminsterhtllercne structure (as is strongly indicated by recent experiments), the present Raman measurements together with the four observed IR frequencies give a complete set of Raman and infrared active fundamental frequencies for this molecule. A comparison of this set with the calculated spectrum for buckminsterfullerene shows satisfactory agreement.

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
