CIRRIS 1A observation of13C16O and12C18O fundamental band radiance in the upper atmosphere

Autor: J. R. Winick, W. A. M. Blumberg, J. A. Dodd, J. R. Lowell, P. S. Armstrong, S. J. Lipson

Publikováno v: Geophysical Research Letters. 20:2683-2686

Fundamental band emission from the ν=1 levels of isotopically substituted 13C16O and 12C18O has been observed for the first time in the earth's atmosphere. High-resolution earthlimb spectra were obtained in the Cryogenic Infrared Radiance Instrument

Publikováno v: Geophysical Research Letters. 20:305-308

Individual OH(ν,N) rotational state population column densities have been derived from spectral analysis of CIRRIS 1A nighttime earthlimb airglow data. Both pure rotation and vibration-rotation fundamental spectra have been examined, providing uniqu

Infrared emissions arising from the reactions of FAST O/O+with N2

Autor: G. E. Caledonia, W. A. M. Blumberg, B. L. Upschulte, D. B. Oakes

Publikováno v: Geophysical Research Letters. 19:993-996

We have performed a laboratory investigation of the infrared emissions arising from the interaction of a fast beam of O/O+with N2 over the velocity range of 8 to 12 km/s. Emissions from the ground state vibration-rotational bands of both NO and NO+ a

Publikováno v: Journal of Physics B: Atomic and Molecular Physics. 19:3327-3332

The authors have measured rates for the excitation of vibrational levels 2-7 of the A 2 Pi u state of N2+ by electron impact on N2 relative to each other and to N2+(B 2 Sigma u+, v'=0). These rates are consistent with Franck-Condon factors for ionisa
