Differences between Raman and Fluorescence (in terms of density matrices and Feynman diagrams)

[@Tomas.Malina]

You should think over what you want to say before shooting a video, but this actually helped me, thank you! (Also, a side-professional curiosity - looking at your fingers, you should eat more zinc.)

Glad to hear it helped. It's a way that made clear sense to me so I thought it make sense to view it in this light for others so I wanted to share. I have never broke a finger so I guess lucky me :D

[@SaurabhShukla_22]

hey this video really helped, I really have half baked understanding of feynmann diagram and these processes. Can you answer me a questions (perhaps a stupid one), why do you draw the arrows the way you do in both these processes, like in the Raman one, you take it up and bring it down, then do the same with the conjugate state, while in Fluorescence you take both the ket states up, and then bring the conjugates down? why ? I don't get this !

@heisenbergsdog1630 Can you please share the reference material on the density matrix evolution in raman spectroscopy

a bit confusing
