Pi parameters determined from least-square fits to the hemoglobin MRD data using a series of six terms of the heteronuclear interaction of Eq. 10 with fixed correlation times of 5 × 10−8, 5 × 10−10, 1 × 10−10, 5 × 10−11, 1 × 10−11, and 5 × 10−12 s

The tabulated Pi parameters represent the normalized fractional contribution to the total paramagnetic MRD profile for its corresponding fixed correlation time. The results of the analysis are illustrated in Figs. 4 and 5 for the residual water in the methemoglobin and cyanohemoglobin samples, respectively.
