A nitroxide-maleimide spin label.
was chemically bonded to poly-L-lysine and to bovine serum albumin (BSA) and showed a paramagnetic resonance spectrum that was sensitive to known structural changes in these molecules, such as those produced by changes in pH.2 This nitroxide-isocyanate is unfortunately not an ideal spin-labeling reagent since it is unstable and thus difficult to purify, and moreover the isocyanate group is rapi...
متن کاملHeme-Spin Label Studies of Hemoglobin
In order to investigate the protein conformation in the vicinity of the heme and the spin states of the heme-iron in dissolved hemoglobins, a nitroxide spin label was covalently attached to one of the propionic acid groups of the porphyrin ring. The optical spectra of the heme-spin labeled ferrihemoglobins were identical to those of native hemoglobins indicating that the spin labeling did not a...
متن کاملSpin state switching in iron coordination compounds
The article deals with coordination compounds of iron(II) that may exhibit thermally induced spin transition, known as spin crossover, depending on the nature of the coordinating ligand sphere. Spin transition in such compounds also occurs under pressure and irradiation with light. The spin states involved have different magnetic and optical properties suitable for their detection and character...
متن کاملSpin glass freezing in Kondo lattice compounds
It is presented a theory that describes a spin glass phase at finite temperatures in Kondo lattice systems with an additional RKKY interaction represented by long range, random couplings among localized spins like in the SherringtonKirkpatrick (SK) spin glass model. The problem is studied within the functional integral formalism where the spin operators are represented by bilinear combinations ...
