Katı durumdaki glycine tertbutyl ester hydrochloride and L-α-alanin eter ester’de oluşan serbest radikallerin similasyon metodu ile incelenmesi
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
