The conversion of (551) to compounds (552)-(554) was accomplished in the straightforward manner shown in Scheme 48. The preparation of T-shaped 9-S -3 7t-sulfuranyl radicals permitted Electron Spin Resonance and Electron Spin Echo studies <86JA3206,86JA3211). 

Other methods, e.g. electron spin echo studies [Na 82a, b] have led also to the determination of solvation numbers.

Electron spin-echo studies indicate that pink uteroferrin s unpaired electron interacts with at least one and possibly two classes of nitrogen nuclei, one of which is the imidazole nitrogen of an iron-coordinated histidine These results support similar conclusions drawn from NMR studies showing histidine ligation to both ferrous and ferric ions of the binuclear cluster . Recent ENDOR experiments have also detected N hyperfine interactions with the S = 1/2 center of uteroferrin, presumably due to the remote nitro-gen(s) of an iron coordinated histidine(s) ... 

As single crystals are not available in conducting polymers, the use of the spin echo technique is more complicated and interpretation of the data is quite model-dependent. However, electron spin echo studies of spin dynamics in polyacetylene were reported in the early 1980s [30]. The results on the soliton diffusion rate, which were not consistent with those obtained by the other methods, gave rise to a long controversy. They were recently carefully discussed and invalidated [31].
