Oxygen emissions

Alzeta states that their TPUs can achieve 99.99% destruction with emissions of nitrogen oxides and carbon monoxide of <10 parts per million (ppm) corrected for 3% oxygen emissions. They also state the Alzeta systems prevent the formation of dioxins and furans, and are available with several different operating systems and capacities for different site requirements. 

The fullerene triplet quantum yields in 8 72 were determined by the quantitative conversion of the triplet excited states of the porphyrin (0.78) and fullerene (i.e. 0.98) fragments into singlet oxygen. By analyzing the singlet oxygen emission at 1275 nm (see Fig. 8.22), we derived a quantum yield of 0.84. 

Comparison is made in Fig. 27 of prediction and measurement of atomic oxygen emission as a function of altitude. The oscillations in the measured data are due to precession of the vehicle that occurred during flight. The agreement between the BSUV-2 data and prediction is particularly good at high altitude. As with nitric oxide emission, the radiation at high altitude is found to be sensitive to the gas-surface interaction model. At 90 km, there... 

Reaction (12) is also the primary source of atomic oxygen emissions in Earth s day and nightglow spectra.

It was observed that the injection of a hydrocarbon when the background level of oxygen emission at 777.2 nm was monitored produced a negative response. This behaviour may arise from reduction by carbon of lead oxides which are released from the inner wall of the discharge tube by the action of the plasma in a reaction analogous to that discussed by Crowley et al for several metal oxides in a fuel-rich oxygen-acetylene flame. This suggestion is consistent with...

Osmann et al. [33] investigated the Renner A X A" system of HO2, and used Eqs. (4—8) to represent their ab initio DMSs and TDMS (five surfaces) of this molecule computed with MRD-CI (Davidson-corrected) employing the cc-pVTZ basis sets both for oxygen and hydrogen atoms as well as the effective core potential (ECP) for oxygen. Emission spectrum at T =350 K was simulated, vibrational transition moments were eomputed and tabulated, see Fig. 4.
