Raman Spectroscopy is a powerful analytical technique used to identify molecular composition and structure. It works by shining a laser light on a sample, which causes the molecules to scatter the light. Most of the scattered light retains its original energy, but a small portion changes energy due to interactions with the molecules. This energy change provides unique information about the molecular vibrations, allowing scientists to determine the chemical makeup of the sample. This technique is widely used in various fields, including chemistry, biology, and material science. It is particularly valuable because it requires minimal sample preparation and can be performed on solids, liquids, and gases.
