Electronic and Spatial Structures of Water-Soluble Dinitrosyl Iron Complexes with Thiol-Containing Ligands Underlying Their Ability to Act as Nitric Oxide and Nitrosonium Ion Donors

Figure 1

The first recordings of 2.03 signal: dry yeast cells (A) [10]; wet yeast cells and rabbit liver (B, spectra a, and b, c). Three components of hyperfine structure of EPR signal of Mn ions in MgO sample are shown in spectrum c [14]; rat liver carcinoma induced by p-dimethylaminoazobenzene (butter yellow) (C, spectrum b; (a) spectrum from normal liver) [11]; (D) livers from rats maintaining 7, 14, 21, 35, and 49 days on a diet containing butter yellow [13]. Recordings were made at ambient temperature (A, D) or at 77K (B, C).
