WebSpontaneous Rayleigh‐Brillouin scattering spectra in nitrogen have been measured in the pressure range from 4 to 7 bar at a wide temperature from 291 to 399 K with a scattering angle of about 90°, and then fitted to different theoretical models (S6, V3, and G3). WebWhat is Rayleigh and Mie scattering? Rayleigh line refers to the unshifted central peak observed in the spectroscopic analysis of scattered light. Mie scattering refers primarily to the elastic scattering of light from atomic and molecular particles whose diameter is larger than about the wavelength of the incident light.
