Rayleigh scattering intensity
WebRayleigh scattering law states that the amount of scattering of light is inversely proportional to the fourth power of the wavelength. It is given by: This implies that in case of shorter wavelength, light is more likely to be … WebA Raman spectrum (Figure 6) is defined by plotting the intensity of this “shifted” light versus frequency results in a Raman spectrum of the sample. Generally, Raman spectra are plotted with respect to the laser frequency such that the Rayleigh band lies at 0 cm-1. On this scale, the band positions will lie at frequencies that

WebFluorescence intensity was measured across emission wavelengths 300–600 nm (resolution 4.63 nm) at excitation wavelengths from 250 to 450 nm, with 5 nm increments and an integration time of 1 s. EEMs were corrected for inner-filter effects and for Raman and Rayleigh scattering (Murphy et al., 2013).
