Nuclear Magnetic Relaxation and Self Diffusion in a Series of p-Alkanoyl-Benzylidene-P'-Aminoazobenzenes

Abstract

The self diffusion coefficients and the proton relaxation times have been measured in dependence of temperature in a series of p-alkanoyl-benzylidene-P'-aminoazobenzenes. Together with the frequency dependence of the relaxation rate of p-dodekanoyl-benzylidene-p'-ami9noazobenzene it could be shown that order fluctuations as well as the translational diffusion process contribute to the relaxation rates.
