The report below summarizes the fundamental concepts from Principles of Nonlinear Optical Spectroscopy
Why not just stick to easy linear stuff? Because nonlinear spectroscopy allows you to see: Connectivity: Are these two vibrations linked? The report below summarizes the fundamental concepts from

Bottom Line: Don't get bogged down in the Greek letters. Mukamel is essentially describing a conversation between light and matter. The pulses are the questions, and the signal is the molecule’s answer. The pulses are the questions, and the signal
"The first hit starts a vibration. The second hit catches that vibration mid-swing and changes its direction. The third hit creates a 'signal'—a fourth sound that only happens because of the first three. If the drum is warped, or if there's a second drum nearby vibrating in sympathy, that fourth sound will tell you how they are talking to each other."
