Electron Paramagnetic Resonance (EPR) spectroscopy, also known as Electron Spin Resonance(ESR) especially among physicists, is a strong and versatile spectroscopic method forinvestigation of paramagnetic systems, i.e. systems like free radicals and most transition metalions, which have unpaired electrons. The sensitivity and selectivity of EPR are notable andintriguing as compared to other spec...
متن کاملOxide Surface Analysis of Nickel Based Chromium Alloys with the Aid of Auger Electron Spectroscopy
Auger Electron Spectroscopy (AES) has been used to study the surface compositions of three types of nickel based chromium alloys. These alloys are IN600, IN601 and C22. AES analysis indicated the presence of chromium and oxygen on their surfaces. The formation of this chromium oxide surface layer, 3 nm thick, provides excellent corrosion resistance. For alloy C22, no molybdenum was indicated on...
متن کاملElectron - impact spectroscopy of acetaldehydea >
Acetaldehyde has been studied by the technique of low-energy variable-angle electron energyloss spectroscopy. With this method the low-lying spin-forbidden transitions have been located via the behavior of the relative differential cross sections, providing the first identification by this technique of such states in acetaldehyde. High-lying states were also investigated and some assignments of...
