Negative ion formation from ClCH{sub 2}COCl, CCl{sub 3}CoCl, and ClCH{sub 2}CHO under low-energy (0-10 eV) and monochromatic (0.2 eV) electron impact is studied by using a quadrupole mass filter and a trochoidal electron monochromator. Most of the ions produced are due to a dissociative attachment process and show resonance structure as the energy of the electron is varied. Cl{sup {minus}} ion is the dominant ion and is produced near 0.0 eV. Other ions, resulting from cleavage of C-Cl or C-H bonds, are also observed. Appearance potentials of RCO{sup {minus}} ions resulting from cleavage of a C-Cl bond are 1.0, 0.4, and 0.2 eV for acetyl chloride, chloroacetyl chloride, and trichloroacetyl chloride, respectively.

Mass spectrometric study of negative ions from unsaturated carbonyls Hacaloğlu, Jale; Gökmen, Ali; Baumgartel, H. (1989-01-01) Negative ion formation from some unsaturated carbonyl derivatives is investigated as a function of electron energy by using a monochromatic (0.2 eV) and low-energy (0-10 eV) electron beam and a mass spectrometer. Negative ions at low energies are formed via a dissociative attachment process. Appearance potentials of certain negative ions can be correlated with the electron-releasing or -withdrawing power of the substituents and/or with bond strengths. For example, the appearance potentials of C6H5CO" and C2...
Electrochemical Behavior of Hydrazine Borane in Methanol Solution Ozhava, Derya; Önal, Ahmet Muhtar; Özkar, Saim (The Electrochemical Society, 2014-01-01) Electrochemical behavior of hydrazine borane (HB) was investigated on gold electrode in 0.5 M LiClO4 solution in methanol using cyclic voltammetry, electrochemical impedance spectroscopy (EIS) and chronoamperometry. Two irreversible peaks at 164 and 530 mV are attributed to direct electro-oxidation of HB on gold electrode in methanol. Both EIS results and CV data at different scan rates indicate a diffusion controlled electron transfer reaction. Furthermore, the Tafel slope (b = 0.191 V) and charge transfer...
Short-range correlations in a one-dimensional electron gas Tas, M; Tomak, Mehmet (American Physical Society (APS), 2003-06-15) We use the Singwi-Sjolander-Tosi-Land (SSTL) approximation to investigate the short-range correlations in a one-dimensional electron gas. We find out that the SSTL approximation satisfies the compressibility sum rule somewhat better than the more widely used Singwi-Tosi-Land-Sjolander approximation in the case of a one-dimensional electron gas.
Antioxidant enzyme activities in rat liver tissues of diabetic rats Sadi, Gökhan; Güray, Tülin; Department of Biochemistry (2004) Free radicals are the compounds having one or more unpaired electrons in their outer orbital and this unpaired electron make these compounds very reactive. Especially as their concentration increases, they initiate a chain oxidation reaction of lipids, proteins and nucleic acids. The condition, in which the production of free radicals exceeds their elimination or tissue defense mechanism decrease against them or both occur together, is called oxidative stress. In diabetes mellitus which is a glucose metabol...
Mass spectrometric study of negative ions from acetyl derivatives Hacaloğlu, Jale; Suzer, S. (1989-01-01) A mass spectrometic technique capable of producing a low-energy and nearly monochromatic (fwhm ~ 0.2 eV) electron beam is developed and used to study the negative ions from five different acetyl derivatives CH3COX (X = Cl, C6H5, NH2, CH3, and H) at very low energies (0-10 eV). Negative ions are mainly produced by dissociative attachment and show resonance-like structures. To measure the excess energy imparted to the ions during ionization, a time-of-flight technique is applied. An ion with composition C2H30...
