Raman spectroscopy is a vibrational spectroscopic technique which allows compositional analysis of liquids and solids. The technique can be employed to analyse a range of samples (organic and inorganic) to determine structural/compositional changes and identification of unknown samples.
By coupling Raman spectroscopy to light microscopy, spatial resolution down to 1 micron of compositional changes within a sample can be achieved. In addition, confocal Raman microscopy can be used to perform depth-profiling of a sample giving 3-dimensional chemical resolution.
