rare gases การใช้
- This is due to spin-orbital splitting of atoms and ions of rare gases.
- Fluorine and sometimes rare gases possess this ability as well.
- Significant differences between alkali metals and excited rare gases exist in their molecular symmetry.
- Reactions ( 3 ) and ( 4 ) were experimentally demonstrated for all the rare gases.
- The alkali metals have good chemical affinity for halogen and should have affinity for excited rare gases.
- It's not like I'm asking about the diffusivity of some rare gases in each other, after all.
- It is clear that the collisional coupling process induced by the rare gases are not well established.
- In principle all rare gases and rare-gas halogens can form a slightly bound excited state and thus can form excimers.
- For instance, an ammonia plant can churn out food-grade liquid carbon dioxide; hydrogen peroxide and rare gases useas freon and cooling industrial components.
- Experimentally the collision cross section of metastable states of rare gases with the halogens is similar to that of alkali metals with halogens.
- Similarly, the only viable sources of the rare gases neon, krypton, and xenon is the distillation of air using at least two distillation columns.
- The orders of magnitude of k are summarized in Table 30 . k increases with the vibrational level of and heavier rare gases, Rg.
- Other rare gases are cheaper than xenon, but they ( along with their excited species and their ions ) absorb less than xenon at 308 nm.
- In older publications, this analogy that is applicable only for the heavier rare gases, is used to study the behavior of these gases with halogen donors.
- At Brookhaven National Laboratory Dr . Zahringer worked with Dr . Oliver Schaeffer's cosmochemistry group applying mass spectrometry techniques to the study of rare gases in meteorites.
- From one extreme to another, Delage already has chosen his next project : studying rare gases in the stratosphere 43 kilometers ( 27 miles ) above sea level.
- They have shown that the total ionization rate predicted by the PPT model fits very well the experimental ion yields for all rare gases in the intermediate regime of Keldysh parameter.
- They have shown that the total ionization rate predicted by the PPT model fit very well the experimental ion yields for all rare gases in the intermediate regime of Keldysh parameter.
- When they are in a configuration belonging to metastable states np ( n + 1 ) s, ( n = 5 for xenon ), rare gases possess properties of polarizability and elastic scattering similar to those of alkali metals.
- For instance, by separating the total interaction of physisorption into two contributions-a short-range term depicted by Hartree & ndash; Fock theory and a long-range van der Waals attraction, the equilibrium position of physisorption for rare gases adsorbed on jellium substrate can be determined.
