Photoelectron Spectroscopy and the Dipole Approximation
Over the past three decades, the dipole approximation has facilitated a basic understanding of the photoionization process in atoms and molecules. Advances in gas-phase photoemission experiments using synchrotron radiation have recently highlighted nondipole effects at relatively low photon energies while probing the limits of the dipole approximation. Breakdowns in this approximation are manif...
متن کاملThe Potentiodynamic Behavior of Copper in NaCI Solutions Studied by Auger and Photoelectron Spectroscopy
The potentiodynamic behaviour of copper in brine solutions was studies. Auger and photo-electron spectroscopy were used together with electrochemical methods. It is demostrated that the passivation observed in potentiodynamic curves is due to a surface film formation on a copper electrode. It is concluded that this film must be copper (I) chloride in nature. Effect of different factors on poten...
متن کاملHigh-resolution photoelectron spectroscopy
The evolution of photoelectron spectroscopy of neutral molecules in the gas phase from its first applications in the early 1960s to the present day is reviewed with emphasis on the description of methods that have contributed to improve the resolution. In early days, photoelectron spectroscopy was very successfully used to study the electronic structure of molecules. As the resolution improved,...
متن کاملConformation-Selective Resonant Photoelectron Spectroscopy via Dipole-Bound States of Cold Anions.
Molecular conformation is important in chemistry and biochemistry. Conformers connected by low energy barriers can only be observed at low temperatures and are difficult to be separated. Here we report a new method to obtain conformation-selective spectroscopic information about dipolar molecular radicals via dipole-bound excited states of the corresponding anions cooled in a cryogenic ion trap...
متن کاملPhotoelectron spectroscopy of XenI
XenI ÿ clusters n6 13 have been studied by anion photoelectron (PE) spectroscopy at a photon energy of 4.661 eV and an electron energy resolution of 10 meV. Electron anities (EA's) as a function of cluster size are extracted and compared to previous PE and tunable laser photodetachment spectra of these species. The EA's found in this study lie between those of the two earlier experiments. Th...
