Chirp effects on generation of ground state vibrational wave packets in polyatomic molecules are experimentally and theoretically investigated. Theory indicates optimal chirp is quadratic, depends on all displaced modes, and follows the evolving multidimensional potential energy gap. Experiments on 2 organic dyes reveal that 5 fsec pulses are unable to track this evolution, resulting in optimal GVD which maximizes the pulses chirp rate.
