). In nonlinear optics, since we use the density matrix, we have operators acting from both the left and the right (
Nonlinear spectroscopy is simply the art of asking a molecule a question, waiting for it to start answering, interrupting it with another question, and then listening to the confused (but informative) response.
If you take nothing else from Mukamel, learn the diagrams. These are the "Practical Approach" to keeping track of the math. Each diagram tells a story:
). Mukamel’s equations show that by varying these delays, you are actually performing a Fourier Transform on the system's internal dynamics. (Coherence Time): Tells you about the energy gap.
