Broadening of the Rayleigh line which originates in the deformation or chemical reactions of light‐scattering macromolecules is examined. It is shown that a system observing the depolarized component in the forward‐scattering light is useful in order to eliminate the undesirable spectral component of high intensity which comes from the translational Brownian movement of the macromolecule. Relaxation times of the molecular deformation or reactions are shown to be obtainable from the Lorentzian line width of the Rayleigh component.
