Abstract
The dynamic properties of isobutanol are studied in a wide (90–350 K) temperature range by recording the relaxation shifts in the steady-state luminescence spectra of eosin and erythrosine and by kinetic phosphorescent spectroscopy invoking the Cole-Davidson model for dielectric relaxation. The characteristic dipole relaxation times and the activation energy of relaxation processes in the matrix in the temperature range of 140–170 K are determined from the correlation function of the dynamic Stokes shift of the phosphorescence spectrum of luminescent probe molecules.
