Photoelectron Spectroscopy,his phenomenon,originally described by Einstein as the photoelectric effect,nowadays is referred to as photo ionization or (by scientists having physical background) as photoemission. The energetics of the process are simply defined through the relationship:

Electronic Structure of f-Block Compounds,the d-transition series. Figures 1 and 2 illustrate the radial charge density for Pr. and U.. The electronic structure of an fn ion is dominated by different interactions than for the more familiar d-transition ions. In this paper we will review the methods and nomenclature used to describe the electronic structure of f. compounds.

,Organometallic Compounds with Lanthanide — Carbon Sigma Bonds, One of the Last Problems in Organomeempty d-orbitals, i.e. the main group elements and the metals of the Zn-group could be made in this early period. Not until 1952, when the first compound containing a covalent Ti-C-bond was isolated, was the characterization of the first organo-metallic compound containing a carbon — transition metal — σ — bond accomplished (4).

Vibrational Spectroscopy of Some Organometallic Compounds of Actinides,emists, it is very easy to avoid contamination during the preparation of the samples when radioactive materials are handled and the majority of the measurements can be made in a small box with optical windows without risk of contamination of the spectrometer.
