WebFeb 15, 2006 · Until recently, the biological literature on structural colour has obscured the most fundamental physical distinction among all mechanisms of structural colour production: incoherent vs coherent scattering (e.g. Prum and Torres, 2003a; Prum and Torres, 2003b; Prum and Torres, 2004).Incoherent scattering is the differential scattering … 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.
