✦ Synopsis


Five grams of a mixture of C~60~/C~70~ can be separated in 24 hours by gel permeation chromatography on polystyrene gel. The mobile phase can be completely recovered, and the method can be scaled up by a simple increase in the inner diameter of the column.

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
