The Number of High-Energy Bands in the Photoelectron Spectrum of Alkanes
نویسندگان
چکیده
It was observed that within the Bieri-Dill-Heilbronner-Schmelzer model for the calculation of the ionization energies of alkanes CnH2n+2, there are exactly n C2s-electron energy levels lying below the degenerate – manifold. We now show that, indeed, this regularity is obeyed by practically all alkane species. Exceptions do exist, but they must possess a (chemically infeasible) group of more than six mutually connected quaternary carbon atoms.

Investigation of Always Present and Spectrum Sensing based Incumbent Emulators
Cognitive radio (CR) technology has been suggested for effective use of spectral resources. Spectrum sensing is one of the main operations of CR users to identify the vacant frequency bands. Cooperative spectrum sensing (CSS) is used to increase the performance of CR networks by providing spatial diversity. The accuracy of spectrum sensing is the most important challenge in the CSS process sinc...
متن کاملPhotoelectron imaging of I2- at 5.826 eV.
We report the anion photoelectron spectrum of I2- taken at 5.826 eV detachment energy using velocity mapped imaging. The photoelectron spectrum exhibits bands resulting from transitions to the bound regions of the X 1Sigmag+(0g+), A' 3Piu(2u), A 3Piu(1u), and B 3Piu(0u+) electronic states as well as bands resulting from transitions to the repulsive regions of several I2 electronic states: the B...
متن کاملFeasibility of the Application of Moment Of Inertia as a Feature to Study High-Frequency Bands in Brain Signals
Introduction Many features, emerging from mathematical techniques, have been used in the analysis of brain signals. In this study, the physical quantity of “moment of inertia” (MOI) was introduced as a feature to enhance high-frequency waves (HFWs) in electroencephalography (EEG). Materials and Methods In this research, the recorded EEGs from F3, F4, and Cz points in 20 males were used. A total...
متن کاملThe Reactive Chemisorption of Carbon Dioxide at Mg(100) Surface
X-ray photoelectron and electron energy loss spectroscopic (XPS-EELS) studies reveal that the following species are present when a mixture of CO2 and water vapour is exposed to the clean Mg(100) surface at 110K: CO3(a), C(a) CH(a), OH(a). The reactive chemisorptions of CO2 and H2O vapour coadsorbed on a Mg surface ...
