In the monomer, dimer and polymer phase of RbC60, the principal infrared modes exhibit significant shifts and splittings. We compare the positions of the main components of the four T1u modes of C60 in these three phases. The frequency shifts are determined by two competing effects: lattice hardening due to the formation of chemical bonds between the balls, and softening induced by electron-molecular vibration (EMV) coupling. The behavior of the individual modes correlates with their sensitivity to pressure and their EMV coupling constants.
