Calculation of parameters of electron paramagnetic resonance spectra in the strong and weak magnetic fields for nitroxides and spin labels in normalsaline.

Zhukov, Yuri M.

The aim is to study the manifestations of the exchange interaction in nitroxyl radicals.

As a result of the work done on the calculation was obtained by a number of characteristics of the EPR spectra of nitroxyl radicals with interactions, not considered previously.Based on these findings, we conclude the successful simulation of the EPR spectrum of nitroxyl radical in zero field.From the collection of the considered parameters of the system is clearly observed splitting of energy levels in zero field.

As part of this dissertation research was conducted nitroxide spectra in zero field EPR.Made a literature review on the problems of the thesis.The analysis of EPR spectra.During the processing of data was obtained by the splitting of lines in zero field, the wave functions calculated transition probabilities are constructed energy matrix and energy levels are calculated for various cases of the exchange interaction.Also been calculated form the EPR spectrum of nitroxide in the strong and weak magnetic field.
