Abstract

Gama ışınlaması sonucu glycine tertbutyl ester hydrochloride and L-α-alanin
eter ester’de oluşan paramagnetik merkezler belirlenmiştir. EPR
spektroskopisinde elde edilen deneysel spektrumlar, H₂NĊHCO₂C(CH₃)₃.HCl
and CH₃ĊHCOCH₂CH₃ paramagnetik merkezlere
(radikallarine) atfedilmiştir. Bu spektrumlardan elde edilen magnetik değerler
kaydedilmiştir. Paramagnetik merkezlerin oda sıcaklığında 2 ay kararlı
(sönmediği) kaldığı görüldü. Ayrıca, magnetik parametreler ve paramagnetik
merkezin elektronik yapısı similasyon metoduyla doğrulanmıştır.

Simulation Study of Paramagnetic Centers Induced in Glycine Tertbutyl Ester Hydrochloride and L-α-alanine Ethyl Ester in Solid State

Abstract

The paramagnetic
centers formed in glycine tert-butyl ester hydrochloride and L-α-alanine ethyl
ester after irradiated was determined using EPR spectroscopy. The EPR spectra
of the samples were attributed to the H₂NĊHCO₂C(CH₃)₃.HCl
and CH₃ĊHCOCH₂CH₃ radicals,
respectively. The magnetic parameters obtained from the spectra were evaluated.
The spectra were seen to be stable for more than 2 months at 300 K. Magnetic
parameters and the electronic structure of the paramagnetic centers (radicals)
were determined with a simulation method.

Keywords

Electron paramagnetic resonance; paramagnetic center; amino acid; irradiation; simulation method
