Gas phase C₆₀ is resonantly excited using picosecond infrared (IR) pulses from a free electron laser [1]. The excitation can be very high, reaching levels where the thermal emission of electrons from C₆₀ is observed. The excitation is much more efficient when the macropulse of the IR radiation is chirped to lower frequencies. The excitation process is modeled and the results can be compared to the experiment.
