Abstract
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 Mössbauer 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.
