Abstract:

A spectral-spatial 2D ESR imaging system was installed on a Bruker ER 200 D ESR spectrometer. It consists of a pair of field gradient coils, power supplies and a computer system used for image reconstruction. Spectral-spatial 2D ESR imaging was performed on several free radical samples using the filtered back-projection method. The spatial distribution of the spin densities of the free radicals and the corresponding spectral parameters were acquired simultaneously from the 2D images. The relationship between the imaging parameters and the accuracy of the images was discussed.

Key words: ESR, spectral-spatial imaging, free radical, spin density, field gradient
