Abstract

Amino acids of solid state DL-beta-amino-n-butyric acid (BABA), Triethylene tetramine hexa acetic acid (TTHAA) and DL-Asparagine monohydrate (DLAMH) have been investigated by Electron Paramagnetic Resonance Spectroscopy. Free radicals formed in irradiated powder crystals have been examined at temperatures of 300 Kelvin. The structure of the free radical and the hyperfine structure constants were reported. The free radicals formed in the compounds were found to be stable for three months, fifteen days and two months respectively. The obtained results are in agreement with the literature values.

Gama Işınları ile Işınlanmış Amino Asit Türevlerinin EPR ve Simulasyon Metodu ile İncelenmesi

Abstract

Katı durumdaki DL-beta-amino-n-butirik asit, Trietilen terami hekza asedik asit ve DL-asparagin monohidrat aminoasitleri Elektron paramanyetik rezonans spektroskopisi ile incelendi. Işınlanmış toz kristallerde oluşan serbest radikaller 300 Kelvin sıcaklıklarında incelendi. Serbest radikalin yapısı ve aşırı ince yapı sabitleri tespit edildi. Bileşiklerde oluşan serbest radikallerin sırasıyla 3 ay, 15 gün ve 2 ay boyunca stabil olduğu görüldü. Elde edilen sonuçlar literatür değerleri ile uyumludur.
