Discontinuous behavior of Rayleigh relaxation in supersaturated aqueous NH_4H_2PO_4 Solution

The algorithm of Rayleigh intensity correlation is employed for the elucidation of relaxa-tion time constants of the aqueous NH_4H_2PO_4 solution with various concentrations.The resultshows that there is a discontinuous(abrupt)increases in the relaxation time constant as the super-saturation state is reached.This quantity,the relaxation time constant,therefore,can be an orderparameter.Also discussed is the dependence of the relaxation time constant on the aggregationnumber n in(H_2PO_4~-)_n.This dependence is complicated and may be crucial in understanding theaggregation process in the supersaturation state.

Discontinuous behavior of Rayleigh relaxation in supersaturated aqueous NH4H2PO4 solution

The algorithm of Rayleigh intensity correlation is employed for the elucidation of relaxation time constants of the aqueous NH₄H₂PO₄ solution with various concentrations. The result shows that there is a discontinuous (abrupt) increases in the relaxation time constant as the super-saturation state is reached. This quantity, the relaxation time constant, therefore, can be an order parameter. Also discussed is the dependence of the relaxation time constant on the aggregation number n in (H₂PO₄^?)n. This dependence is complicated and may be crucial in understanding the aggregation process in the supersaturation state.
