Sažetak

Chemical relaxation measurements are reported on alkylammonium
halides having carbon atoms in the alkyl chain from 10
to 16. Two relaxation times were observed for most of the studied
systems. Data are interpreted on the basis of a theory recently
developed by G. Aniansson and S. Wall. According to this theory,
the fast process is due to a shift of the micellar distribution curve.
The residence time of a detergent molecule in the micelle and the
half width of the micellar distribution curve are obtained from
the fast process. The slow relaxation process is characteristic for
the change of the concentration of micelles and permits the evaluation
of the concentration of the micellar nuclei and their thermodynamic
properties. The obtained results are compared with
available data on alkylpyridinium halides.
