We show that collective vibrational excitations play a central role in the reaction mechanism of femtosecond laser‐fullerene and fullerene‐fullerene collisions. In particular, we demonstrate the dominant role of the radial symmetric breathing mode in intense fs‐laser pulses and the oblate‐prolate mode in fullerene‐fullerene collisions, respectively. In the first case, the predictions have been confirmed by recent pump‐probe experiments. In the latter case, the present analysis provides a natural explanation of long‐outstanding open questions concerning the experimental observations. The investigations are based on an ab‐initio method, the so‐called nonadiabatic quantum molecular dynamics (NA‐QMD).
