The Raman spectra of an overdamped B.-mode in KH.,.-..D..P0. crystalshave been analyzed with the generalized form of single-mode susceptibility. It hasbeen shown that the absolute value of a pole co. of z(cv) which makes a largercontribution to the line shape, e.g., in case of a damped harmonic oscillator,a pole closest to the origin, is the most appropriate parameter to describe thephase transition regardless of the model adopted in the analysis. The l#.l wasproved to have a linear temperature dependence for any x in the neighborhood ofT.. It is suggested that there exists a critical degree of deuteration x.:0.2, atwhich the mechanism of the phase transition changes qualitatively.
