Rayleigh shift

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). The result of the root‐mean‐square errors of fitting residuals shows that the V3 and G3 models have … Webshifts and converge cubically like the Rayleigh quotient iteration. We now show the equivalence of the “pure” QR algorithm and orthogonal simulta-neous iteration. Recall the …
