UV laser pulse trains for Raman spectroscopy

Optics Letters, 2021
The theoretical framework for a novel, to the best of our knowledge, stimulated Raman spectroscopy process using a UV probe laser pulse train is formulated and simulated. The laser pulse train consists of multi-femtosecond micro-pulses separated by a varying time duration, having a fixed carrier frequency.

UV/Vis Spectroscopy

2009
The π π* transition of conjugated double bonds is above ≈200 nm with typical intensities of the order of log e ≈ 4. Its position can be estimated with the Woodward– Fieser rule.

UV Spectroscopy Analysis for Itraconazole

Journal of Ravishankar University (PART-B), 2023
Itraconazole is a triazole antifungal agent that is synthesised. Itraconazole has been manufactured into a variety of pharmacological formulations and administered in a variety of ways. Itraconazole pills are used to treat pulmonary fungi that can cause fungal infection and spread throughout the body.

UV spectroscopy with SOHO

Advances in Space Research, 2003
Abstract The UV spectroscopy from SOHO has provided new and exciting results from a wide range of phenomena observed on the Sun. Determination of plasma parameters such as velocity, density, temperatures, line widths and abundances have provided new physical insight into fundamental problems in solar physics.

Ultraviolet (UV) Spectroscopy

2019
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.

Resin Bead Micro-UV−Visible Absorption Spectroscopy

Analytical Chemistry, 2005
The construction and design of a microscope coupled with a miniature UV-vis spectrometer is described. This was applied to the study of dyes linked to solid supports and displayed good correlation in spectral shape and lambda(max) values when compared to the dyes in solution, as well as showing a linear relationship between dye loading and UV-vis ...

UV-visible spectroscopy

1998
This chapter evaluates UV–visible spectroscopy. Within inorganic chemistry, the field of study often associated with UV–visible spectroscopy is that of the coloured transition metal complexes. The energies associated with transitions between different arrangements of valence electrons falls within the ultraviolet (UV) and visible region of the ...

Excitation and UV spectroscopy

1985
Excitation means that one electron moves from an occupied orbital ψι to an unoccupied orbital ψ α. This can happen after supply of energy, usually from electrons or photons.

Systematic Organic UV Photoelectron Spectroscopy

Applied Spectroscopy Reviews, 1979
Abstract Photoelectron spectroscopy (PES) provides valuable information on the ionization energies of atoms and molecules. The ionization energy (IE) is given by the relation. hv = IE + T where hv is t h e energy of the radiation and T i s the kinetic energy of the electron. The IEs are directly related to the orbital energies (Koopmans' theorem).
