摘要：

Solid ammonium trisoxalatoferrate(III) has been investigated by Mössbauer spectroscopy, using 57Fe enriched samples. Broadened spectral lines indicating the presence of fast electronic relaxation effects have been obtained in the 80-295 K temperature range. All spectra have been analysed in terms of the Afanus'ev theory of Mössbauer lineshape. The isotropic transverse relaxation model fits best the experimental spectra. A spin-spin type relaxation mechanism is suggested for the broadening of Mössbauer lines. © 1979.
