Nonequilibrium processes in supersonic jets of N2, H2, and N2 + H2 mixtures: (I) Zone of silence.
Number density and rotational temperature in the zone of silence of supersonic jets of N(2), H(2), and their mixtures N(2) + 2H(2) and 2N(2) + H(2), at p(0) = 1 bar and T(0) = 295 K, have been measured by Raman spectroscopy. Translational temperature in the jets has been derived from the experimental data assuming isentropic flow. The density along the jet axis decays at a rate depending on the...
متن کاملNonequilibrium processes in supersonic jets of N2, H2, and N2 + H2 mixtures: (II) shock waves.
We report an experimental study of the shock wave system of three continuous axisymmetric jets of pure N(2) and H(2), and of the N(2) + 2H(2) mixture, generated at p(0) = 1 bar and T(0) = 295 K through a D = 310 microm cylindrical nozzle against a background pressure p(b) = 6.1 mbar. Number density and rotational populations have been measured by Raman spectroscopy with high spatial resolution ...
متن کاملInfrared spectra of CO2-H2 complexes.
Infrared spectra of weakly bound CO(2)-H(2) complexes have been studied in the region of the CO(2) v(3) asymmetric stretch, using a tunable diode laser probe and a pulsed supersonic jet expansion. For CO(2)-paraH(2), results were obtained for three isotopic species, (12)C(16)O(2), (13)C(16)O(2), and (12)C(18)O(2). These spectra were analyzed using an asymmetric rotor Hamiltonian, with results t...
متن کاملH2 Morphology of Young Planetary Nebulae
The distributions of H2 1-0 S(l) emission in the young planetary nebulae BD +30°3639 and NGC 7027 show ~triking similarities: both have limb-brightened arcs of H2 emission with radii that are about twice those of ~h~ir H; II regions. The extended H2 emission in both nebulae is attributed to a photodissociation region. Thi.s implies that the neutral envelopes of these young planetaries extend we...
متن کاملAbove threshold photodissociation in H2 and H2+
A coupled equations approach is used to calculate the probabilities of photophysical processes in the ten photon absorption spectrum of H2 at wavelength A = 532nm At high intensities, ie, I~10~°W/cm~, it is shown that above threshold photodissocianon (ATPD) occurs readily m the B ~3]
