First of all, thank you so much SpectraCat for the kind discussion.
I was thinking of it in the similar way in the first place, however, it kind of confused me when I saw that diamond and graphene (all composed by "atom" with specific orientations in crystal) actually have Raman peaks...
Hi all,
I'm just wondering why pure metals, whatever kinds, do not have Raman peaks. Because the visible light cannot penetrate the metals? If so, what kind of EM wave can penetrate metals? Just need some key words for further information. Of course, I would appreciate if you would explain...
