dynamic structure factor

https://doi.org/10.1351/goldbook.12280
Function describing the temporal dependence of relative scattering intensity on the magnitude of the scattering vector, \(q\).
Note: The value of the dynamic structure factor is characteristic of the various modes of motions of the polymer molecules or the dispersed particles and their parts and is also characteristic of the time-dependent interference of scattering, reflecting ordering of the positions of the scattering entities in time. In dynamic light scattering, it can be derived from the time autocorrelation function.
