Photon Correlation Spectroscopy

Preferred Label : Photon Correlation Spectroscopy;

NCIt synonyms : Dynamic Light Scattering; PCS; DLS;

NCIt related terms : Quasi-elastic Light Scattering;

NCIt definition : A type of spectroscopy that utilizes a laser beam to irradiate a sample containing particles in suspension, resulting in light scattering. Rapid fluctuations in scattering intensity, around a mean value at a certain angle, occur because of particle diffusion and are dependent upon on particle size. The calculated correlation function yields a diffusion coefficient, for a given temperature and viscosity, which can be used to calculate particle size.;

Alternative definition : CDISC: A type of spectroscopy that utilizes a laser beam to irradiate a sample containing particles in suspension, resulting in light scattering.;
