We present a study of the localized vibrational mode of H - ions substituting F - ions in the calcium fluoride lattice. Using a tunable high pressure carbon dioxide laser we determined the linewidth and the saturation intensity of the H - local mode

We perform a comparison of electron affinities (EA) of the conjugated molecules bithiophene, azulene, naphthalene, and their water clusters. Bithiophene and azulene monomers have positive EAs of +49±5 meV and +790±8 meV, but naphthalene has a negat

The charge-transfer process, which is the subject of this paper, is an important link in the chain of reactive events which occur in the E- and F-regions of the earth’s atmosphere. The reaction is suspected to proceed via the formation of a short-l

The widely accepted model descriptions of ion–molecule reactions suggest identical rate constants for the title reaction and the analogous, isoelectronic system N2++H2, which has been the topic of a previous publication from this laboratory. A comp

This article presents detailed internal and kinetic energy dependent cross sections and reaction rates for the hydrogen atom transfer processes N+2(X 2Σ+g, v+=0–4, J+=2)+H2→N2H++H, which were obtained under single‐collision conditions in a gui

In this paper we report on the detection of new far-infrared laser lines from CH3Cl and CH3Br optically pumped with a continuously tunable high pressure CO2 laser. We found 80 new lines for CH3Cl and 9 new lines for CH3Br in the frequency region betw

We report on generation and detection of intense pulsed radiation with frequency tunability in the infrared and far-infrared spectral regions. Infrared radiation is generated with a transversally electrically excited high pressure CO2 laser. A laser

Pressure-induced abnormal line shift, line broadening and spectral intensity variations have been measured in 3-photon enhanced ionization spectroscopy of H2 B1Σu+−X1Σg+ (12−0) and C1Πu−X1Σg+ (2−0) rotational transitions. All of these abn
