摘要：

The long-wavelength part of the electronic absorption spectrum of C70 isolated in a 5 K neon matrix was observed with well-resolved vibrational structure. Its origin lies at 15690 cm-1. The electronic transitions of C70+ and C70- were detected after NeI irradiation of C70 during deposition. C70- has a broad absorption (fwhm almost-equal-to 330 cm-1) centered at 7336 cm-1. The absorption of C70+ is found in the range of 12400 to 14000 cm-1 and assigned to the 2E1'<--2E1'' transition. The spectrum is also discernible by growing a matrix with mass selected C70+ ion beam.
