Photodissociation of carbon dioxide produces O (1S) atoms and CO (a3Π) molecules in the Mars upper atmosphere. Calculations of the emission rate of the atomic oxygen 2972 Å line and the carbon monoxide Cameron bands produced by the photodissociation mechanism are factors of 3 and 10, respectively, smaller than the emission rates observed by Mariner ultraviolet spectrometers. Laboratory measurements are needed to understand the discrepancies.

Abstract. A spectral imager specifically designed to measure the O+(2P-2D) emission in the thermosphere during twilight has been constructed and tested in Toronto (43.8°N, 79.3°W), and found to show promise for long-term and campaign-mode operations. A modification of the mesopause oxygen rotational temperature imager (MORTI), it consists basically of a narrow-band interference filter (0.14 nm bandwidth) to separate wavelengths as a function of off-axis angle, a lens to focus the spectrum into a series of concentric rings, and a focal plane array (CCD) to record the spectral images in digital form. The instrument was built with two fields of view, one for the zenith and one for 20° above the horizon, movable to track the azimuth of the Sun, in order to provide appropriate data for inversion. Data gathered during June 1991 provided measurements of the column-integrated emission rate with a precision of about 3%. An atomic oxygen profile was deduced that showed good agreement with that predicted by the MSIS-90 model atmosphere. Geomagnetically induced variations of the O+ lines, calcium spectra resulting from meteor showers, and OH nightglow were also observed.

Kinetics Of

A simulation is developed to investigate the kinetics of nitric oxide (NO) formation in premixed methane/air combustion stabilized by nanosecond-pulsed discharges. The simulation consists of two connected parts. The first part calculates the kinetics within the discharge while considering both plasma/combustion reactions and species diffusion, advection and thermal conduction to the surrounding flow. The second part calculates the kinetics of the overall flow after mixing the discharge flow with the surrounding flow to account for the effect that the discharge has on the overall kinetics. The simulation reveals that the discharge produces a significant amount of atomic oxygen (O) as a result of the high discharge temperature and dissociative quenching of excited state nitrogen by molecular oxygen. This atomic oxygen subsequently produces hydroxyl (OH) radicals. The fractions of these O and OH then undergo Zel’dovich reactions and are found to contribute to as much as 73% of the total NO that is produced. The post-discharge simulation shows that the NO survives within the flow once produced.

Catalytic Recombination

The air afterglow has been studied in a flow system by mixing the products of a microwave discharge in oxygen with NO or mixtures of gases and by measuring the intensity of the glow immediately past the point of mixing and farther downstream in a long glass tube at known pressure, composition, and linear velocity of flow. The intensity of the greenish yellow chemiluminescence is shown to be proportional to the concentrations of atomic oxygen and nitric oxide, and independent of the nature or amount of added inert gases. An average quantum (5500 Å) is emitted for every 10 7 collisions of O with NO. The concentration of atomic oxygen is determined by a 'titration with NO 2 in which the end-point is indicated by complete extinction of the glow all along the tube, and which is made possible by the great speed of the reaction O + NO 2 → O 2 + NO. Observation of the spatial decay of the glow under steady-state conditions is well suited to the study of reactions of atomic oxygen. The concentration of NO remains constant along the tube because reaction (1) quickly regenerates NO from NO 2 , and the light intensity directly measures the concentration of atomic oxygen. The method is applied to give information on the rates of the reactions O + NO + M → NO 2 + M , O + O 2 + M → O 3 + M , O + SO 2 + M → SO 3 + M , etc. Some results are also presented for the effect on the disappearance of O of the following added gases: N 2 , A, CO 2 , H 2 , CO, N 2 O, C 6 H 8 , SO 3 , Fe(CO) 5 , H 2 O, O 3 , C 2 H 4 , Cl 2 and Br 2 . The rapid catalytic recombination of O by added Cl 2 is discussed in some detail.
