Rayleigh scattering spectroscopy near-resonance Rayleigh scattering spectroscopy near-resonant Rayleigh scattering near-resonance Rayleigh scattering spectrometry near-Rayleigh resonance scattering A method for determining structure by measuring the change in direction or energy of Rayleigh scattered visible light, where the wavelength of the incident light corresponds to an energy which is near to an absorption band in the scattering molecules. near-resonance Rayleigh scattering near-resonance Rayleigh light scattering near-resonant Rayleigh light scattering CHMO:0000173 NRRS NRRLS near-Rayleigh resonant scattering
