Using Hornowski’s theoretical modification of the critical amplitude, the experimental al(crit)/pu(w)2A(T) values from mode-coupling theory of a binary liquid mixture aniline – cyclohexane have been compared with the theoretical expressions given by Fixman, Kawasaki, Mistura, and Chaban. The experimental data at low reduced frequencies w* has been found to agree well with the Hornowski’s model of A(T). However, for the large values of reduced frequency w* > 10 the mode-coupling theory of Shiwa and Kawasaki still exhibits poor agreement with the observed data, mainly due to the form of scaling function. The correlation length x has been calculated by using w00 ( the critical amplitude of the characteristic relaxation rate ) which gives the best fitting to the theoretical critical amplitude. The adiabatic coupling constant g and the diffusion coefficient D have been obtained using Hornowski’s expression of the critical amplitude.
