Relaxation Time Constants

Electron spin resonance imaging is a technique using similar principles to the established nuclear magnetic resonance imaging; however, the very fast electron-spin relaxation time constants of the former are an experimental challenge. In order to obtain T2-weighted as well as functional images spatially resolved in the micrometer range, we use temperature-dependent pulsed X-band ESR and the back-projection reconstruction method. We present here recent results of our imaging project focussing on quasi one-dimensional organic conductors, where even pulsed conduction electron-spin resonance is possible.

Permittivity Measurements

Abstract The dielectric loss and electron spin resonance linewidth of ferric acetylacetonate have been measured in dilute solutions of benzene, m-and p-xylene, mesitylene and carbon tetrachloride. Permittivity measurements were made at 10 frequencies in the microwave region (1.2 m to 1 mm wave-length), ESR measurement at 2 frequencies (X and Q band). The permittivity results show a broad non-Debye pattern, yielding a mean correlation time of about 4 ps. The ESR results yield a mean correlation time of about 3 ps. The parallelism between the results obtained by both methods is discussed in view of a common relaxation process, which is the transient deformation of the chelate system resulting from stochastic induction by neighbouring solvent molecules.
