Rayleigh-gans
WebFIGURE 5.71 The Rayleigh-Debye-Gans theory is based on the assumptions that (1) the incident beam propagates without being affected by the particles, and (2) the scattered hght, received by the detector, is a superposition of the beams emitted from the induced dipoles in the different parts of the particle. [Pg.301] WebThe Rayleigh–Gans approximation is a means of interpreting MALS measurements with the assumption that the scattering particles have a refractive index, n 1, very close to the refractive index of the surrounding medium, n 0.

WebSep 25, 2024 · With Rayleigh scattering, g = 4. However, our liposomes are comparable in size to the wavelength of the light we use to study them and empirically, we find g < 4. As outlined below, Gans and Debye modified Rayleigh scattering giving the Rayleigh-Gans-Debye (RGD) approximation (Meeten 1981; Mikati et al. 1987; van de Hulst 1981).

Rayleigh–Gans approximation, also known as Rayleigh–Gans–Debye approximation and Rayleigh–Gans–Born approximation, is an approximate solution to light scattering by optically soft particles. Optical softness implies that the relative refractive index of particle is close to that of the surrounding … See more The validity conditions for the approximation can be denoted as: $${\displaystyle n-1 \ll 1}$$ $${\displaystyle kd n-1 \ll 1}$$ $${\textstyle k}$$ is the wavevector of the light ( See more • Mie scattering • Anomalous diffraction theory • Discrete dipole approximation See more Rayleigh–Gans approximation has been applied on the calculation of the optical cross sections of fractal aggregates.

WebA light scattering theory known as the Rayleigh-Gans theory was developed to extend Rayleigh theory to particles that are not optically small. The correction method involves extrapolation techniques that extrapolate light scattering intensity to zero scattering angle. This correction technique is important for analyzing results on polymer ...
