By studying the temporal behavior of the optical density of C60 thin film with the help of femtosecond laser spectroscopy the coherent phonon oscillations in the frequency region 10 - 400 cm-1 (including with odd symmetry) in the wide spectral region of probing h(omega) pr equals 1.78 divided by 2.34 eV was detected. Spectral dependence of photoinduced response permits to observe selectively the relaxation of electrons in different bands. The possibility of reversible polymerization in excited state is discussed.
