We have measured the near-infrared absorption spectrum for isolated C60- ions at room temperature. Two bands, at 9145  cm-1 and 10460  cm-1, have been identified in addition to the main absorption band at 9382  cm-1, seen also at low temperature in a matrix. An interpretation based on the theory of dynamic Jahn-Teller effects is proposed.
