Atomic Energy Levels and Other Spectroscopic Data
The key advances in our understanding of atomic structure were made early in the 20th Century. Niels Bohr developed his revolutionary theory of the hydrogen atom in 1913, still largely on classical terms. Then, in the 1920s, the generalization to other atoms and ions came with the development of quantum mechanics, or wave mechanics, by Schroedinger, Heisenberg and others, after de Broglie postu...
متن کاملAtomic Force Microscopy: probing the Nanoworld
Atomic Force Microscope and related techniques have played a key role in the development of the nanotechnology revolution that is taking place in science. This paper reviews the basic principles behind the technique and its different operation modes and applications, pointing out research works performed in the Nanometric Techniques Unit of the CCiTUB in order to exemplify the vast array of cap...
متن کاملSpectroscopic Evaluation of the Atomic Size
A new algorithm for evaluating the atomic size is suggested by entailing the atomic spectroscopic data-the wave number. The basic tenet of the present method is (i) to convert a multi-electron atom system to a hydrogenic atom to invoke the Bohr model for the mechanism of electron transition, and (ii) to use the experimental atomic spectroscopic data of multi electron systems to determine the at...
متن کاملFT-IR and NMR Spectroscopic Investigation and Hybrid Computational DFT/HF Analysis on the Molecular Structure of NSPD
Compound (N,N-bis (salicylidene) 1,2-diaminophenylene) was prepared by condensation of ethanolsolution of 2-Hydroxybanzaldehyde and 1,2-diaminophenylene. The compound was characterized by1H NMR, infrared spectroscopy (FT-IR) data and analytical data. The geometrical parameters andenergies have been obtained from Density Functional Theory (DFT) B3LYP method and Hartree-Fock (HF) method with 3-21...
متن کاملAN FT-IR SPECTROSCOPIC INVESTIGATION OF IONIC SOLVATION OF ALKALINE EARTH CATIONS WITH DIMETWYLSULFOXIDE IN ANHYDROUS ACETONITRILE
The interaction between DMSO and alkaline earth perchlorates in anhydrous acetonitrile was investigated by FT-IR spectroscopy. A quantitative study was performed to determine the average number of bonded DMSO molecules using v (SO) and v (C-S) vibrations. Changes in coordination numbers were observed both with increasing atomic numbers and the solvent composition. None of the investigated...
