Spin probe, formula

General regularities of molecular dynamics and local organization of micellar phase of polyelectrolytes complexes with ionic SAS [16-22, 26] were formulated for the solution of this problem spin probes were used. Formulas of some of the last ones are presented in Scheme 3. 

In this appendix we shall provide exphdt expressions for the recursion formulas of Eq. (3.13) for the case of a nitroxide spin probe and a copper complex in solution. To this end we need these preliminary definitions ... 

The structural state of membranes was studied by EPR-spectroscopy using paramagnetic spin probes [8], Rat and mice blood erythrocytes and mice EAC cells were incubated in the presence of ichfan for 45 min then, probes were inserted. The microviscosity of various membrane sites was measured on an ER 200D-SRC spectrometer (Bruker, Germany). Probe I (2.2.6.6-tetramethyl-4-capryloyl-oxypiperidine-l-oxyl) is localized mainly in the surface lipid bilayer of membrane probe II (5.6-benzo-2.2.6.6-tetramethyl-1.2.3.4-tetrahydro-y-carboline-3-oxyl) permeates into deep-located near-protein sites of the lipid bilayer. From the EPR spectra obtained, using the formula for rapidly rotating probes, the rotation correlation time...
