Abstract
We have analyzed the Mössbauer spectra of a highly anisotropic low-spin ferric compound, [Fe(TICOH)2](BF4)3, taken in frozen solution as a function of temperature and field. Unlike other low-spin ferric compounds, [Fe(TICOH)2](BF4)3 shows a sharp six-line pattern with an overall s;litting of 14.2 mm/s in an applied field at 4.2 K. Good simulations are obtained using the model of Oosterhuis and Lang with a crystal field of axial symmetry. At higher temperature spin fluctuations become important, and a dynamic lineshape model with temperature- and field-dependent relaxation rates is used to simulate the data.
