Mitigation of electron attachment to oxygen in high pressure air plasmas by vibrational excitation

Journal Article Frederickson, K ; Lee, W ; Palm, P ; ... - Journal of Applied Physics

A series of time resolved microwave attenuation measurements are performed of the electron number density of an electron beam generated, CO laser excited nonequilibrium O{sub 2}/N{sub 2} plasma. Resonant absorption of infrared radiation from the CO laser produces the nonequilibrium state, in which the heavy species vibrational modes are disproportionately excited, compared to the rotational and translational modes (T{sub vib}{approx_equal}2000-3000 K vs T{sub R} at {sub {approx}}{sub sol{approx}} at {sub T}{approx_equal}300 K). It is shown that this results in an increase in the plasma free electron lifetime by two orders of magnitude compared to the unexcited cold gas, an effectmore »« less

Relaxation processes in a nitrogen plasma. II. Population of the vibrational levels of the B/sup 3/II/subg/ and C/sup 3/II/subu/ states and relaxation of the gas temperature

Journal Article Eroshchenkov, E K ; Malkin, O A - Sov. Phys. - Tech. Phys. (Engl. Transl.); (United States)

A spectral method with a time resolution of approx.1 ..mu..sec is used to study the population kinetics of the excited levels of the N/sub 2/ molecule in the C/sup 3/..pi../subu/ and B/sup 3/..pi../subg/ states and to study the rotational temperature T/subr/ during the development of an rf induction discharge at a pressure of 0.1 torr. The mechanisms for the level population are discussed. (AIP)
Vibrational relaxation of NO in collisions with atomic oxygen and chlorine

Journal Article Glaenzer, K ; Troe, J - J. Chem. Phys., v. 63, no. 10, pp. 4352-4357

The vibrational relaxation of NO(X$sup 2$II) in the $nu$ = 0, 1, and 2 states in collisions with Ar, NO, NO$sub 2$, and electronic ground state O and Cl atoms has been studied in shock waves. O and Cl atoms were produced in the thermal dissociation of NO$sub 2$ or N$sub 2$O at T approximately equal to 2700 K, and of ClNO at T approximately equal to 1700 K, respectively. Both atoms were found to be very efficient catalysts for vibrational energy transfer to NO. The relaxation rates observed suggest a mechanism involving bound (NO$sub 2$)* and (ClNO)* collision complexes.more » (auth)« less

Vibrational pseudo-diffusive motion of the oxygen octahedra in La{sub 2}CuO{sub 4} and Sr doped La{sub 2}CuO{sub 4} from anelastic and {sup 139}La NQR relaxation

Journal Article Cordero, F ; Campana, A ; Corti, M ; ... - International Journal of Modern Physics B

The vibrational dynamics in nearly stoichiometric La{sub 2}CuO{sub 4+{delta}} has been studied by means of anelastic relaxation and by {sup 139}La NQR relaxation. Evidence of dynamical tilting of the octahedra in a double well local potential is obtained with both the experimental techniques. Anelastic relaxation at the quadrupole frequency {nu}{sub Q} {approximately} 19 MHz occurs at T {approximately} 330 K. The data are analyzed in terms of a model of pseudo-diffusive cooperative motion. The measured effective barrier is 2800 K, higher than the one of the local potential because of the cooperative character of the motion. Upon Sr doping themore »« less
