Abstract
The values of the Rayleigh ratio of two pure liquid, toluene and benzene, at various wavelengths have been collected from the literature, and a correlation between the Rayleigh ratio and the wavelength in the form of power law has been developed for each liquid and can be used to compute accurately the Rayleigh ratio at any wavelength between 420 and 700 nm. The Rayleigh ratio scales with the wavelength with a power of −4.17 and −4.38, respectively, for toluene and benzene, which deviate significantly from the Rayleigh law (−4.0). However, if the effect of the wavelength on their refractive indexes is accounted for, the power is reduced to −4.0 and −4.2 for toluene and benzene, respectively.
