چکیده
|
The zwanzig theory of dielectric friction was applied to s- acetylthiocholine halides and perchlorate in different pure solvents at 30°c. the resulting points for the given ions in different solvents were found to be scattered around the straight lines. the scattered values may be attributed to the uncertainty in the values of the relaxation time (τ ). the values of the radius from slope (hydrated radius) and intercept (hydrodynamic radius) were increase with increasing the size of ions,while the values of the slope greater than the values of the intercept may be due to the solvation of the ions. such differences were investigated and discussed on the basis of the assumptions of zwanzig theory.
