Electron Spin Resonance of Free Radicals and Radical Pairs in Irradiated Single Crystal of 1-Methyluracil
ion radical 1 After irradiation of single crystals at room tem perature abstraction and addition radicals of types 1 and 2 give rise to a complex composite ESR spec trum. Annealing for about 20 min at 200 °C or storage for about two months at room temperature greatly simplifies the spectral pattern indicating the survival of the abstraction radical only. The same spectrum is also seen after i...
متن کاملElectron spin resonance of an irradiated single crystal of Guanine hydrochloride dihydrate.
In their observations of the electron spin resonance (ESR) of irradiated nucleic acids and their constituents in the powdered form, Shields and Gordy' found a triplet caused by two equally coupling protons in guanine and deoxyguanosine. Later, this was interpreted by Gordy, Pruden, and Snipes2 as arising from a radical formed hy hydrogen addition to the C(8). The interpretation was later proved...

چکیده پایان نامه (شامل خلاصه، اهداف، روش های اجرا و نتایج به دست آمده): کار جمع آوری گو یش های محلی در سال های اخیر شتاب امیدوار کننده ای به خود گرفته است. شاید از بارزترین اهداف جمع آوری گویش های مختلف، ثبت و ضبط آن، جلوگیری از نابودی و مهمتر از همه حل مشکلات دستوری زبان رسمی باشد. دقت در فرآیند های زبانی گویش های محلی نوع ارتباط مردم نواحی مختلف با پیرامون نشان را به ما نشان خواهد داد. از س...
Identification of primary free radicals in trehalose dihydrate single crystals X-irradiated at 10 K.
Primary free radical formation in trehalose dihydrate single crystals X-irradiated at 10 K was investigated at the same temperature using X-band Electron Paramagnetic Resonance (EPR), Electron Nuclear Double Resonance (ENDOR) and ENDOR-induced EPR (EIE) techniques. The ENDOR results allowed the unambiguous determination of six proton hyperfine coupling (HFC) tensors. Using the EIE technique, th...
متن کاملElectron Spin Resonance of VO2+ in LiKSO4 Single Crystals
Lithium potassium sulfate, LiKSO4, belongs to the family of compounds LiMAB4 (M=Na,K,Rb,Cs,NH4; AB4=SO4,BeF4). LiKSO4 has been investigated in great detail because of its large variety of physical properties found in different structural phases [1, 2]. This paper reports the electron spin resonance (ESR) of vanadyl, VO, ion impurities in single crystals of LiKSO4 at 295 K. The crystal structure...
