ESR study and copolymer analysis of acrylamide-methacrylamide solid solutions Baysal, Bahattin M. (Wiley, 1988-3) When acrylamide‐methacrylamide mixed crystals are irradiated by ultraviolet (UV) rays, a copolymeric sample is obtained containing both monomeric constituents. For identification and quantitative analysis of these copolymers, a modified form of UV spectroscopy was used. The greatest advantage of UV spectroscopy for copolymer analysis lies in its rapid application. A comparison of the spectrum of the unknown compositions with spectra of known systems by using a calibration curve and the shifts in absorption ...

ESR and conductivity investigations on electrochemically synthesized polyfuran and polythiophene Demirboga, B; Önal, Ahmet Muhtar (2000-06-01) ESR studies have been carried out on ClO4--doped polyfuran (PF) and BF4--doped polythiophene (PT) films synthesized by constant potential electrolysis. Variation of spin concentration and linewidth of ESR signal with temperature were investigated. The temperature dependence of conductivity supported the Mott's variable range hopping mechanism for PT and PF freestanding films. Temperature dependence of activation energy indicated that hopping is the dominating mechanism of charge transport.
ESR dating of calcrete nodules from Bala, Ankara (Turkey): Preliminary results Kucukuysal, Ceren; Engin, Birol; Günal Türkmenoğlu, Asuman; Aydas, Canan (Elsevier BV, 2011-02-01) The age of two calcrete nodules (C1 and C2) from the Bala section in the region of Ankara, Turkey, is determined by the Electron Spin Resonance (ESR) method. Three radiation-induced ESR signals at g=2.0056 (A signal), g=2.0006 (C signal) and g=2.0038 (broad signal, BL) were observed. The broad signal (BL) intensity was used as a dating signal. The properties of this dating signal are described in this manuscript. The calcrete nodules were irradiated with a Co-60 gamma source and measured with an ESR spectro...
