Electronic and infrared spectra of C +60 and C -60 in neon and argon matrices
Abstract
The electronic transitions of C +60 and C -60 isolated in 5 K neon matrices were detected with well-resolved vibrational structure after NeI irradiation of C 60 during deposition. On the basis of a C +60 spectrum obtained by growing a matrix with a mass-selected C +60 ion beam, overlapping peaks in the electronic spectra were assigned to either C +60 or C -60. The vibrational frequencies 1406 and 1332 cm -1 for C +60, and 1386 and 1202 cm -1 for C -60, were identified in a neon matrix from the infrared spectrum. C -60 was also detected after codepositing Na and K with C 60, without irradiation. Relevance of the data to interstellar observations is discussed.
