UV-NIR absorption spectra recorded for matrixes with two different charge state ratios of C. A: C in Ne matrix. B: C in Ne+1% CO2 matrix. B comprises much more C than A. The inset shows weak absorptions of C60. C shows the difference spectrum resulting from subtraction of A from B. D shows the reference UV spectrum of neutral C60 in Ne+1% CO2 matrix.
