Kinetics of Micellization from Ultrasonic Relaxation Studies — The Fast Process Described by the Two State Model

Theory of ultrasonic absorption in micellar solutions

“…Previous investigations of the ultrasonic absorption amplitude, ^max either have been based on a reverse assignment of the two relaxation processes15 or have not taken adequate account of the finite width of the size distribution. 14 In spite of this, the concentration dependence of ^max, as predicted by these authors, agrees qualitively with the one predicted in this paper, showing, however, measurable quantitative differences.…”
