    Intramolecular structure and dynamics of mequinol and guaiacol in the gas phase: Rotationally resolved electronic spectra of their S{sub 1} states. Identifying the emitting species in luminol chemiluminescence in aqueous solutions is an example of such an investigation. The product of the oxidation of luminol is 3-aminophthalate. The maximum emission wavelength in these conditions is nm, which corresponds to the maximum wavelength of fluorescence emission from the 3-aminophthalate. @article{osti_, title = {The electronic structure of VO in its ground and electronically excited states: A combined matrix isolation and quantum chemical (MRCI) study}, author = {Hübner, Olaf and Hornung, Julius and Himmel, Hans-Jörg}, abstractNote = {The electronic ground and excited states of the vanadium monoxide (VO) molecule were studied in detail.

A general discussion held at Queens College, University of St. Andrews, Dundee, 2~3 April, Determination of the s t r u c t u r e s. In the past, a great deal of effort has been devoted The structure of electronically-excited species in the gas-phase book the analysis of the role of electronically excited species in different gas-phase reactive systems [1–12], as far as the electronic excitation can substantially modify molecular properties, particularly, reactivity [13–15].Molecular nitrogen excited to the lowest The structure of electronically-excited species in the gas-phase book electronic state is quite interesting species for the following.

Our observations imply that production of #Work Cited by: Carbon gasifi- cation results from electronically-excited oxygen (initially present) and carbon dioxide, while carbon deposition processes seem to involve carbon monoxide and other species still richer in carbon.

It is conceivable that this mechanism for carbon deposition might lead to problems in the operation of graphite by: 1. The electronically excited states of actinide species are often at low The structure of electronically-excited species in the gas-phase book energies that they must be included in thermodynamic calculations.

In reactions yielding electronically excited products, more than one po­ tential surface is involved, and kinetic studies of the associated chemilumi­ nescence can yield information about the.

These electron-atom and electron-molecule collisions can create a range of species in the gases including positive and negative ions, electronically excited states of the atomic and molecular species and dissociated fragments such as atoms and radicals that may be in their ground or higher energy electronic by: In the context of atomic orbitals, an open shell is a valence shell which is not completely filled with electrons or that has not given all of its valence electrons through chemical bonds with other atoms or molecules during a chemical reaction.

Atoms generally reach a noble gas configuration in a molecule. The noble gases (He, Ne, Ar, Kr, Xe, Rn) are less reactive and have configurations 1s 2. A large section is devoted to electronically excited states, ionic species, and free radicals, relevant to chemical sys­ tems. In addition recent advances in gas phase polymerization, formation of clusters, and energy release processes in energetic materials were presented.

Vibronic spectra involve simultaneous changes in the vibrational and electronic energy states of a molecule. In the gas phase vibronic transitions are accompanied by changes in rotational energy also. Vibronic spectra of diatomic molecules have been analysed in detail; emission spectra are more complicated than absorption spectra.

The intensity of allowed vibronic transitions is governed by. Gas phase reaction rates have been measured for the reactions of Cl−, I−, OH−, O2−, SF6, and some hydrates of Cl−, OH−, and O2− with atomic hydrogen in a flowing afterglow system at.
