Electronic state spectroscopy of C2Cl4

Nondissociative low energy electron attachment to C2Cl4 :C2Cl4

The lifetimes of long-lived parent anions formed by nondissociative electron attachment to C2Cl4 are investigated using Rydberg atom techniques. The ions are created through electron transfer in collisions with K(np) Rydberg atoms and their lifetimes are measured using both time-of-flight techniques and a permanent magnet Penning trap designed specifically for heavy ion storage. The data show t...

Iodopentafluorobenzene: electronic state spectroscopy by high resolution vacuum ultraviolet photoabsorption and photoelectron spectroscopy

The electronic transitions of iodopentafluorobenzene (C6F5I) have been investigated experimentally for the first time by high-resolution photoabsorption spectroscopy in the energy range 3.6 – 10.7 eV. The character of the valence excited states has been discussed taking into account calculations available in the literature. The ionisation energies of the molecule in its electronic ground state ...

Electronic spectroscopy of carbon chains.

Investigators have recorded the electronic spectra of assorted carbon-chain systems in the gas phase using a variety of methods, ranging from direct cavity ringdown absorption spectroscopy to photofragmentation techniques that utilize the cooling capabilities of an ion trap. We summarize the results from these studies and compare them with astronomical measurements of the diffuse interstellar b...

Electronic Spectroscopy of Diatomic Molecules

In vitro study of drug-protein interaction using electronic absorption, fluorescence, and circular dichroism spectroscopy

In the near future, design of a new generation of drugs targeting proteins will be required. Considering the complex bond between the drug and protein, the structure and stability of the target protein should be considered. So far, a series of in vitro investigations have been conducted with the aim of predicting drug-biological medium interactions. In these studies, use of spectroscopic method...
