Absolute spin-flip raman laser frequency measurements with metal-insulator-metal diodes

Autor: G. E. Streit, J. S. Wells, F. R. Petersen

Publikováno v: Optics Communications. 19:248-252

Infrared frequency synthesis techniques with metal-insulator-metal (MIM) diodes have been extended to include absolute frequency measurement of a spin-flip Raman laser (SFRL). As a result of this extension, spectroscopy in the 5.3 μm region more rea

Reactions and quenching of vibrationally excited hydroxyl radicals

Autor: G. E. Streit, Harold S. Johnston

Publikováno v: The Journal of Chemical Physics. 64:95-103

Rate constants for the deactivation of vibrationally excited hydroxyl radicals by the inert gases Ar, O2, N2, H2, and D2 have been determined. Additionally the rate constants for the reaction HO(v)+O3→ products have been measured and found to decre

Atmospheric chemistry of aldehydes: enhanced peroxyacetyl nitrate formation from ethanol-fueled vehicular emissions

Autor: Antonio H. Miguel, Roger L. Tanner, J. B. de Andrade, G E Streit, J S Gaffney

Publikováno v: Environmental Science & Technology. 22:1026-1034

A preliminary study of the effects of enhanced acetaldehyde emissions from vehicles using ethanol and ethanol-containing fuel on peroxyacetyl nitrate (PAN) concentrations in urban air has been conducted in Rio de Janeiro. During this study, part of t

Absolute rate constant determinations for the deactivation of O(1D) by time resolved decay of O(1D) →O(3P) emission

Autor: Carleton J. Howard, J. A. Davidson, D. A. Jennings, H. I. Schiff, C. M. Sadowski, G. E. Streit, A. L. Schmeltekopf

Publikováno v: The Journal of Chemical Physics. 64:57-62

Absolute rate constants for the deactivation of O(1D) atoms by some atmospheric gases have been determined by observing the time-resolved emission of O(1D) at 630 nm. O(1D) atoms were produced by the dissociation of ozone via repetitive laser pulses
