Depolarized low-frequency(LF) Raman spectra of AX (A=Li, Na, K, Rb, Cs; X=Cl, Br, I) aqueous solutions have been investigated over a wide concentration range. The reduced spectra were analyzed with one relaxation function based on the multiple random telegraph(MRT) model and two damped harmonic oscillators. One of the fitting parameter, Kubo number α0, corresponding to the modulation speed in the MRT model is found to be a good indicator of the structure making and breaking effects for water by ACl and ABr.
