https://doi.org/10.1351/goldbook.L03477
Any technique in which a specimen is bombarded with a finely focused @[email protected] beam (diameter less than $$10\ \unicode[Times]{x3BC}\text{m}$$) in the @[email protected] or @[email protected] range and the intensity versus @[email protected] function of the Raman radiation is recorded yielding information about vibrational states of the excited substance and therefore also about functional groups and chemical bonding.
