Mukamel treats nonlinear spectroscopy as a problem of input and output. The input is your set of laser pulses, and the output is the macroscopic polarization of the sample. The bridge between them is the . For a third-order ( χ(3)chi raised to the open paren 3 close paren power ) experiment, the response function Everything else (solvent molecules, lattice vibrations, etc
How fast does energy move from point A to point B? Everything else (solvent molecules
Nonlinear spectroscopy fixes this. It is not magic—it is interrogation . You hit the sample with multiple laser pulses, wait, and ask specific questions. and ask specific questions.
