The fine structure of the Rayleigh line due to molecular scattering in liquids has been investigated with a Fabry-Perot interferometer and the two fine structure components identified for the first time with this instrument. The agreement between the observed and calculated values of the displacements of these new fine structure components is particularly good, in the case of the liquid used (Benzene). The dependence of the frequency shift of the displaced components from the central main line on the frequency of the incident radiation has also been verified in complete agreement with Brillouin’s equation. Photographic reproductions of the interference patterns obtained with the three lines of Hg,i.e.,λ 4358 Å, λ 4078 Å and λ 4047 Å have been included in the paper from which one can clearly identify the two fine structure components due to molecular scattering as is to be expected from Brillouin’s theory. It is found that the central undisplaced component is distinctly brighter than the two side components due to scattering. |
