Bu çalışmada 300 K sıcaklıkta L-prolin ve L-serin tozlarında Gama ışınlaması sonucu oluşan elektron paramanyetik rezonans (EPR) spektrumlarının belirlenmiş, aynı zamanda radikallerin kararlılıkları ve yapıları incelenmiştir. Örneklerin deneysel EPR spektrumları CH3ĊH ve CH2ĊNH2 radikallerine atfedilmiştir. EPR spektrumları beş aydan fazla değişmeden kalmıştır. Burada tartışılan radikallerden elde edilen sonuçların literatür verileri ile uyumlu olduğu görülmüştür.

In this work, electron paramagnetic resonance (EPR) spectra of gamma irradited L-proline and L-serine powders have been examinated at 300 K, as well as to determine their stability and radical structures. The EPR of samples were attributed to the CH3ĊH and CH2ĊNH2 radicals. The EPR spectra were seen to be stable for more than five months. The results obtained from the radicals discussed here were observed to be in good agreement with the literature data.
