Two-dimensional normal distribution of zero field splitting parameters for EPR spectra of human serum transferrin
https://doi.org/10.26907/mrsej-25202
Abstract
n approximation of a distribution of zero field splitting (ZFS) parameters by using two-dimensional normal distributions in discrete representation is proposed. The results of modelling the X-band EPR spectra of human serum transferrin are in a good accordance with experiment. For a number of studied EPR spectra, it was found that the desired distribution consists of two components with various rhombicity parameters. The first component is characterized by a relative high degree of correlation between the parameters E and D. For the second component of ZFS, which we associate with iron bound to the C-lobe iron site of human serum transferrin, a high dispersion of the correlation coefficient is observed.
