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.","code":"P97","type":"DEFINITION","source":"NCI"}],"properties":[{"code":"P322","type":"Contributing_Source","value":"CDISC"},{"code":"P366","type":"Legacy Concept Name","value":"Photon_Correlation_Spectroscopy"},{"code":"P106","type":"Semantic_Type","value":"Laboratory Procedure"},{"code":"P207","type":"UMLS_CUI","value":"C1882368"}]}
