Relaxation as seen by nuclei: Comparison between conventional Moessbauer spectra and nuclear resonant scattering of synchrotron radiation
Description
The mechanism of spin-lattice relaxation has been investigated in the 'picket-fence' porphyrin [Fe(CH3COO)(TPpivP)]-, a high-spin iron(II) complex with unusual large quadrupole splitting of 4.25 mm s-1, by conventional Moessbauer spectroscopy as well as by nuclear resonant forward scattering (NFS). Superparamagnetism with a blocking temperature of about 8 K is observable by both methods in the spectra of bacterioferritin from S. olivaceus. From these two examples general conclusions about the merits of both methods can be drawn
