60Co- ışınları ile ışınlanmış menadion (2-metil-1,4-naftokinon; K3 vitamini; C11H8O2) tek kristallerindeki radyasyon hasar merkezleri, 120 K'de Elektron Paramanyetik Rezonans (EPR) spektroskopisi ile incelenmiştir. Bileşikte, iki radikalin varlığı tespit edilmiştir. Her iki radikal de karbon-merkezli radikaldir. Üç farklı eksen boyunca gama ışınlanmış menadion tek kristallerinin EPR spektrumlarının analizi, bileşiğin C(11)-H(19) bağının kırıldığını göstermiştir. Eşlenmemiş elektronun, C(11) atomu üzerinde bulunduğu belirlenmiştir. Menadion tek kristalinde gözlenen radyasyon hasar merkezlerinin g değerleri ve aşırı ince yapı sabitleri elde edilmiştir. Simülasyon çalışması ile, deneysel verilerin doğruluğu gözlenmiştir.

Electron Paramagnetic Resonance Study of the Radiation Damage Centers in Menadione Single Crystal

Öz

The radiation damage centers in the 60Co- rays irradiated menadione (2-methyl-1,4-naphthoquinone; Vitamin K3; C11H8O2 ) single crystals were examined at 120 K by Electron Paramagnetic Resonance (EPR) spectroscopy. The presence of two radicals was detected in the compound. Both radicals are carbon centered radicals. Analysis of the EPR spectra of gamma-irradiated menadione single crystals along three different axes showed that the C(11)-H(19) bond of the compound was broken. It was determined that the unpaired electron located on the C(11) atom. The g values and the hyperfine structure constants of the radiation damage centers observed in menadione single crystal were obtained. Accuracy of experimental data was observed by simulation study.
