A diagram has two vertical lines (left = ket, right = bra). Time goes up. Arrows point toward the molecule (absorption) or away from it (emission).
[ k_signal = -k_1 + k_2 + k_3 ]
He is solving for all possible directions, but in 90% of experiments, you only care about the rephasing (echo) direction. Ignore the rest until you are a pro. Principle 4: Feynman Diagrams for the Practically Confused Mukamel loves double-sided Feynman diagrams. They look like spaghetti on mirrors. Here is how to fix them: A diagram has two vertical lines (left = ket, right = bra)
