The study of intermolecular energy transfers in electronic energy quenching for molecular collisions N2-N2, N2-O2, O2-O2
Contributions of intermolecular electron energy transfers in the electronic quenching are calculated for molecular collisions N2(A6 u , W 1u)+N2(X6 g , v=0), N2(A6 u )+N2(X 16+ g , v≥0), N2(A 36+ u )+O2(X 36− g , v=0– 2), O2(a1g , b16+ g )+O2(X 36− g , v=0–2). The calculation has allowed one to estimate the product branching ratios. It is shown that there is a dependence of the calculated rate ...
متن کاملEffect of annealing in O2 or N2 on the aging of Fe0.5Mn1.84Ni0.66O4 NTC-ceramics
Fe0.5Mn1.84Ni0.66O4 NTC ceramic thermistors were annealed in nitrogen or oxygen atmosphere at 600°C. The change of the electrical properties of the thermistors with time was reduced sharply by annealing in N2, whereas it was enhanced upon annealing in O2. N2-annealed samples exhibited a less degree of redistribution of cations in the lattice as compared with O2-annealed samples. The aging of th...
متن کاملIonization of N2 , O2, and linear carbon clusters in a strong laser pulse
Multiphoton ionization of linear molecules is studied using the strong-field S-matrix approach. Numerical calculations for the angular distribution and the energy spectrum of the photoelectron as well as the total ionization rates and yields in an intense linearly polarized laser pulse are performed. Results are obtained for molecules aligned along the polarization axis and for ensembles of mol...
متن کاملMolecular effects in the ionization of N2, O2, and F2 by intense laser fields
In this paper we study the response in time of N2, O2, and F2 to laser pulses having a wavelength of 390 nm. We find single-ionization suppression in O2 and its absence in F2, in accordance with experimental results at l=800 nm. Within our framework of time-dependent density functional theory we are able to explain deviations from the predictions of intense-field many-body S-matrix theory sIMST...
متن کاملA Global Climatology of O2⋅O2, O2⋅N2, and (H2O)2 Abundance and Absorption
Recent experimental and theoretical results show that the collision pairs, O2⋅O2 and O2⋅N2, absorb a small but significant fraction of the globally incident, solar radiation (Pfeilsticker et al. 1997, Solomon et al. 1998, Mlawer et al. 1998). The contribution of the water vapor dimer to shortwave (SW) absorption, however, remains speculative due to uncertainties in both its abundance and its ab...
