WebCoherent anti-Stokes Raman spectroscopy, also called Coherent anti-Stokes Raman scattering spectroscopy ( CARS ), is a form of spectroscopy used primarily in chemistry, physics and related fields. It is sensitive to the same vibrational signatures of molecules as seen in Raman spectroscopy, typically the nuclear vibrations of chemical bonds. WebApr 23, 2016 · In incoherent scattering, the phase-shift between the incident plane wave and the scattered spherical wave for each nucleus is random. As in coherent scattering, each nucleus is the point source of a spherical wave, and the array of point sources creates a family of spherical waves that superpose.
