In micro Raman spectroscopy, a laser is focused through a microscope onto a tiny area of the sample. The scattered light is collected and analyzed to yield a Raman spectrum, which is a plot of scattered light intensity versus energy shift. This energy shift corresponds to the vibrational energy levels of the molecules in the sample. The spectroscopy technique is non-destructive and can be performed on a variety of sample types, including solids, liquids, and gases.
