Visible and Ultraviolet Spectroscopy
1994The energies associated with the visible and ultraviolet (UV) regions of the electromagnetic spectrum range from 160 to about 585 kJ/mol. Such energies are sufficient to cause electronic transitions within molecules and to ionize many substances. The electrons involved are the outer or bonding electrons, and the nomenclature used to describe the ...

Spectroscopy in the Vacuum Ultraviolet
1966Publisher Summary This chapter focuses on the recent results and interpretations from vacuum ultraviolet spectroscopy that are of fundamental interest to atomic and molecular physics, or have relevance to collisional or radiative transfer processes in laboratory or astrophysical plasmas.

Ultraviolet Photoelectron Spectroscopy
2018UPS is a photoelectron spectroscopy technique using photons in the ultraviolet region (typically from 10 to 150 eV) as an excitation source. The technique is used to study valence electronic structures of solid surfaces, molecular orbital energies of adsorbed species and work functions of the surfaces and their changes induced by the adsorption of ...

The discussion of Ultraviolet (UV) spectra is based on the characteristic absorption arising from the transition of different types of electrons in organic molecules. Mainly, there are three types of electrons s, p, and p electrons that are commonly encountered in organic molecules.

Ultraviolet Stellar Spectroscopy
1988Many objects which emit X-rays are also sources of uv emission from plasmas at temperatures between 104 and 2 × 105 K. To obtain a full understanding of, for example, stellar coronae, simultaneous studies in the uv, far uv and X-ray regions are ideally required.

Ultraviolet and Visible Spectroscopy
Ultraviolet and Visible spectroscopy was one of the first instrumental methods for analysis. It may be used to characterise a wide range of materials. The UV-Vis provides information based on the degree of absorption or transmittance of a variable wavelength of beam light and sample responses.openaire +1 more source
