Scattering spectroscopy ADVERTISEMENTS: The following points highlight the top sixteen techniques used in cell biology. Raman spectroscopy is commonly used in chemistry to provide a fingerprint by which molecules can be identified. In select instances, a variety of definitive spectroscopic techniques may provide sufficient characterization (for example, if many of the nuclei are NMR active), but in the majority of cases evidence for elemental constitution must be provided by either elemental analysis (e.g., combustion analysis, microprobe analysis), or mass spectrometry. It provides a precise measurement method which requires no external calibration. Raman spectroscopy (/ r m n /) (named after Indian physicist C. V. Raman) is a spectroscopic technique typically used to determine vibrational modes of molecules, although rotational and other low-frequency modes of systems may also be observed.
