Abstract:It is shown that at high magnetic fields the Gd$\sp{3+}$ ion itself serves a sensitive probe for the microenvironment. This sensitivity allows, for example, observation of pH changes and measurement of partitioning of the lipophilic Gd$\sp{3+}$ complexes within the phospholipid membranes. Variations in the width and apparent g-factor of the Gd$\sp{3+}$ EPR spectra with the microenvironment observed at high fields are interpreted as changes in the zero field splitting of the complex. This argument is supported by multifrequency EPR data from 9 to 249 GHz.
