We present a method to determine system-bath correlation functions from third order optical coherence measurements. The importance of these correlation functions for understanding solvation dynamics is explained. A physical argument is made to explain why one coherence measurement, the photon echo peak shift, should strongly reflect system-bath dynamics. Finally, this method is applied to the system of bacteriochlorophylla in tetrahydrofuran solution.
