dc.description.abstractIn this study, the radicals produced by gamma irradiation was determined using ESR technique in cholesteryl octanoate (C35H60O2), a cholesterol ester, which has medical importance. The samples that crystallized in ethanol solution were irradiated with 60Co-source. The molecules that have diamagnetic property become paramagnetic after irradiation. ESR spectra were recorded in different microwave powers and different temperatures at 10 degrees intervals in the magnetic field applied along each of the perpendicular axes using JEOL JESFA-300 X-band ESR spectrometer located in Selcuk University Advanced Technology Research and Application Center. By considering the chemical structure and ESR spectra of Cholesteryl octanoate molecule, it was identified that radiation produced stable and long lived radical, R-CH 3 alpha CH beta CH2 gamma in the sample. The hyperfine splitting and spectroscopic splitting values which have anisotropic property due the location of crystal in the magnetic field were obtained. In addition, simulations were made for identified radical and a good agreement was found with the experimental spectra.en_US
