Abstract

The electron paramagnetic resonance of irradiated single crystal of 4-Methyl Benzylamine Glyoxime(4-MBG) has been observed and analysed for different orientations of the crystals in a magnetic field. 4-MBG single crystal has been investigated at the temperatures between 100 and 400 K. The spectra were found to be temperature independent. Principal values of the g and the hyperfine splitting tensors and their direction cosines are given in the Table 1. The average values of g-factor and the hyperfine splittings were found to be g = 1,999, aN = 14G , aH (NH ) = 13,5G and aCH 7,5G 2 = respectively. The measurements indicate that N(NH) = 0,5 and H(NH) = 0,5 of the unpaired electron are localized on nitrogen and hydrogen respectively. The g-values and the hyperfine coupling constants of the unpaired electron with the protons and nitrogen were determined by EPR and simulation technique.

Özet

Gama ışınlarına maruz bırakılan 4-Metil Benzilamin Glioksim (4-MBG) tek kristallerinin elektron paramanyetik rezonansı, manyetik alanda kristalin farklı yönelimleri için gözlenmiş ve analiz edilmiştir. 4-MBG tek kristalleri 100 K ve 400 K arasındaki sıcaklıklarda incelenmiştir. g-faktörünün ortalama değeri ve aşırı ince yapı yarılmasının değerleri sırası ile g=1,999, , ve olarak bulunmuştur. Çiftlenmemiş elektronun rN(NH) = 0,5 ve rH(NH) = 0,5 ile sırasıyla azot ve hidrojen üzerinde lokalize olduğunu ölçümler göstermiştir. Çiftlenmemiş elektron ile protonlar ve azotun g değeri ve aşırı ince yapı etkileşme sabitleri EPR ve simülasyon tekniği ile belirlenmiştir.
