Depolarized Raman band

{
  "id": "MLC-T-CHM-003026",
  "term": "Depolarized Raman band",
  "field": "Chemistry",
  "definition": "A band in a Raman spectrum whose intensity is largely independent of the polarization of the scattered light relative to the incident light. Such bands are characteristic of non-totally symmetric molecular vibrations. The degree of depolarization is quantified by the depolarization ratio, which for a depolarized band has a value of 0.75 when using linearly polarized incident light.",
