    Electron paramagnetic resonance of gamma irradiation damage centres in acetyl and carbamyl-?-methyl choline chloride
    (Science Reviews Ltd, 2003) Osmanoglu, S; Baskan, MH
    The EPR spectra of gamma-irradiated powders of acetyl-beta-methyl choline chloride (AbetaMCCl) and carbamyl-beta-methyl choline chloride (CPMCCl) indicated the existence of the [Me3NCMeCH2OCOMe]Cl radical in the former and of the [Me3NCMeCH2OCONH2]Cl radical in the latter.

    EPR of gamma irradiated N?-monochloroacetyl-?-aminoisobutyric acid
    (Verlag Z Naturforsch, 2004) Baskan, MH; Osmanoglu, S
    Electron paramagnetic resonance of gamma-irradiated single crystals of N-alpha-monochloroacetyl-alpha-amino-isobutyric acid were investigated at room temperature and 130 K. The paramagnetic center as attributed to the (CH3)(2)CCOOH radical.

    EPR of gamma irradiated single crystal of 2,2-dimethyl succinic acid
    (Verlag Z Naturforsch, 2002) Osmanoglu, S; Baskan, MH; Güner, T
    The EPR technique has widely been used to identify the damage centers produced by high energy radiation [1, 2, 3]. The present work deals with 2,2-dimethyl succinic acid, 2,2-DMSA, HOOCCH2C(CH3)(2)COOH. Free radicals, produced by gamma irradiation of single crystals, were investigated between 120 and 300 K with EPR spectra. The spectra were taken at 10-degree intervals for magnetic fields B applied in each of the three crystallographic planes, ab, bc, and ca. The spectra were independent of temperature. The g value and hyperfine coupling change, when the crystal is rotated around the axes a, b and c, and therefore are anisotropic.

    EPR of gamma irradiated single crystals of N-acetyl- and N-carbamyl-?-aminoisobutyric acid
    (Verlag Z Naturforsch, 2003) Osmanoglu, S; Baskan, MH
    The (CH3)(2)CCOOH radical has been observed in the EPR spectra of gamma-irradiated single crystals and powders of N-acetyl-alpha-aminoisobutyric acid and N-carbamyl-alpha-aminoisobutyric acid.

    EPR of gamma-irradiated L-glutamine hydrochloride and N-carbamoyl-L-glutamic acid
    (Walter De Gruyter Gmbh, 2005) Osmanoglu, S; Aydin, M; Baskan, MH
    The electron paramagnetic resonance spectra of y-irradiated L-glutamine hydrochloride and N-carbamoyl-L-glutamic acid single crystals have been investigated at room temperature. Radiation damage centres are attributed to CH, NH2 and CH2C(NH2)COOH radicals.
