Nitrogen and carbon monoxide

The isoelectronic molecules N2 and CO are conveniently discussed together. Comprehensive investigations of N2 and CO have been made using both the (e-ion)25 and (e,2e)171 methods to probe the broad spectral features of the oscillator-strength distributions for both ion formation and [Pg.54]

It can be seen from Fig. 25 that there is no evidence for any significant increase in oscillator strength at the A -ionization edge in the CO+ + spectrum, and this, in part, may well be the result of PCI (see Refs. 152-155 and also section V.B). Similar results were obtained for nitrogen,173 but the interpretation is less certain because of the superimposition of N+ and N2++. More definitive quantitative work on the inner-shell [Pg.56]

The two higher onsets indicated in Fig. 31 correspond to the maxima of the only other two prominent bands recorded in that region in the (e,2e) PES simulation experiment171 (see following paragraph). The breakdown picture (Fig. 31) has been described25 as follows. [Pg.61]

In the case of CO (see Fig. 32, which shows the sum of the C+ and 0 + oscillator strengths) a rather more complete picture of the dissociative ionization breakdown can be constructed since the C22 state oscillator strength has been measured in the (e,2e) experiment171 in addition to other higher states. In Fig. 32 the total C+ +0+ oscillator strength measured in the (e,ion) experiment25 is compared with the (e,2e) partial oscillator [Pg.62]

The 52S state of CO+ has been the subject of several independent studies. The partial oscillator strength for CO + (Z 2S) can be derived from the following experiments (1) the (e,2e) experiments of Van der Wiel and [Pg.67]

Whereas determination of chemisorption isotherms, e.g., of hydrogen on metals, is a means for calculating the size of the metallic surface area, our results clearly demonstrate that IR studies on the adsorption of nitrogen and carbon monoxide can give valuable information about the structure of the metal surface. The adsorption of nitrogen enables us to determine the number of B5 sites per unit of metal surface area, not only on nickel, but also on palladium, platinum, and iridium. Once the number of B5 sites is known, it is possible to look for other phenomena that require the presence of these sites. One has already been found, viz, the dissociative chemisorption of carbon dioxide on nickel. [Pg.110]

Novacon An adsorptive process for removing oxides of sulfur and nitrogen, and carbon monoxide, from combustion gases. The adsorbent is an active form of natural marble. [Pg.191]

Sconox A catalytic process for oxidizing oxides of nitrogen and carbon monoxide. The catalyst is in the form of a ceramic honeycomb coated with platinum and containing potassium carbonate. The platinum oxidizes the carbon monoxide to carbon dioxide, and the potassium carbonate absorbs the NO,. Developed in 1995 by Sunlaw Energy Corporation, CA, and Advanced Catalytic Systems, TN. [Pg.238]

There is no simple explanation for the much more pronounced instability to pressure of CO compared to N2. Since the only structural difference arises from the heteroatomic character of CO, one could expect that the molecular dipole moment increases with pressure leading to a higher compressibility of CO. But no evidence for this is obtained from either the ab initio calculation or experimentally. In fact the equation of state of nitrogen and carbon monoxide are practically coincident in the pressure range of interest. One other point of interest is the head-to-tail disorder present in carbon monoxide because it has been observed in several high pressure experiments that defects and disorder can play an important role. [Pg.174]

These two rings are virtually unknown. One German patent report of a 1,2,3-oxadiazetidine was later shown to be a methoxymethyl methylnitrosamine (73TL2671). An ab initio calculation (STO-3G) of the decomposition of nitrosyl cyanide to give nitrogen and carbon monoxide discusses the possibility of a 1,2,3-oxadiazetidine carbene as an intermediate (78AJC2349). [Pg.486]

Pluto, with a diameter of 2300 km, has now been demoted from the smallest planet to one of the largest Kuiper belt objects. Pluto and its satellite Charon could be considered a binary system because they are closer in size than any other known celestial pair in the solar system and the barycenter of their orbits does not lie within either body. There are also two smaller moons, Nix and Hydra. All four bodies are likely KBOs with similar compositions. Pluto has a thin atmosphere containing N2, with minor CH4, CO, and Ar. Curiously, the face of Pluto oriented towards Charon contains more methane ice, and the opposite face contains more nitrogen and carbon monoxide ice. [Pg.416]

On heating tetryl at 120°C at reduced pressure (a few mm Hg) the gas evolved in the early stages of the experiment consisted almost entirely of nitrogen and carbon monoxide. [Pg.53]

Porous polymers containing various metal chelates bound to nitrogen functionalities have been used to separate oxygen from argon, nitrogen, and carbon monoxide [25]. The porous polymer is synthesized with pyridyl functional groups, which serve as an axial base for the metal chelate in coordinate bond formation between the metal chelate and the polymer. It also serves to activate the metal complex for oxygen coordination. [Pg.47]

A demethanizer fractionation tower is frequently positioned first. This tower is often operated at 34 x 105 Pa, with temperatures low enough to obtain liquid methane. This tower is usually a tray-type column, although more recently packed towers have been introduced. The noncondensible gases (hydrogen, nitrogen, and carbon monoxide) and relatively pure methane can thus be separated from the C2 and higher hydrocarbons. [Pg.545]

The yellow compound, which decomposes at 80°C., releasing hydrogen, is soluble in benzene, toluene, and tetrahydrofuran. It reacts with a wide variety of inorganic and organic compounds and with many simple molecules such as oxygen, nitrogen, and carbon monoxide. [Pg.21]

The same sample of AlP04-5 was used to obtain the results shown in Figure 12.13. Here, the isotherms of methane, argon, nitrogen and carbon monoxide and the corresponding net adsorption energies were determined at 77 K after the adsorbent had teen outgassed by CRTA to 353 K. [Pg.428]

The energetic heterogeneity shown by nitrogen and carbon monoxide at low loading is clearly evident and is probably due to specific interactions with hydroxyl groups and defect sites. With argon, nitrogen and carbon monoxide, the adsorbate-... [Pg.428]
