Electron Magnetic Resonance of Triplet States and the Detection of Energy Transfer in Crystals

The interaction of L-aromatic aminoacids with bases and nucleosides is described.Of these, ʟ-tryptophan interacts more strongly with bases and nucleosides as indicated by nuclear magnetic resonance, circular dichroism and solubility measurements.A possible ring-ring type interaction between the aminoacid and bases or nucleosides is proposed; this interaction being such that the hydrodinamic behaviour of the DNA molecule is unchanged.Ultra violet irradiated DNA is protected by ʟ-tryptophan. A mechanism of energy transfer from the DNA to tryptophan trough triplet-triplet states is discussed.

Magnetic Inclusions

AbstractArrays of magnetic nanowires and well-oriented chains of superparamagnetic nanoparticles were fabricated using polymer and alumina membrane templates. The systems were characterized by SQUID and studied by electron magnetic resonance methods. Comparative analysis of the obtained results for different geometries and sizes of the magnetic inclusions is presented.
