Tabulated standard values of absolute intensities of a great number of spectral lines are shown to be in excellent agreement with the formula. It is suggested that the two methods of analysis can be useful in spectrochemical research for identification of spectral lines and determination of atomic ...
An empirical formula for the wave numbers of various lines of certain spectral series such as neutral hydrogen and alkali metals; it states that the wave number of thenth member of the series is λ∞-R/(n+a)2, where λ∞is the series limit,Ris the Rydberg constant of the atom, andais...
In the 1880s, Rydberg worked on a formula describing the relation between the wavelengths in spectral lines of alkali metals. He noticed that lines came in series and he found that he could simplify his calculations by using the wavenumber (the number of waves occupying a set unit of length...
The comparisons suggest using the more compact width expression from kinetic theory, which includes initial correlations and a systematic screening of the radiator–perturber interactions, as the starting point for second-order width calculations. 展开 ...
Our result for the line intensity is in agreement with the high-resolution transmission molecular absorption database value but 1.4% smaller. It was applied to partial pressure measurements of <formula formulatype="inline"><tex>$hbox{CO}_{2}$</tex></formula> in <formula formulatype="inline"...

However, it is also important to study the electric-field dependent transport properties in widely used ohmic-contact nanowire devices where the assumption of carrier diffusion dominance is invalid. Here we derive an analytic formula for scanning photocurrent profiles in such ohmic-contact nanowire ...
The large number of overlaps found suggests the existence of strong masers for high-J v=0 and v=1 SiS transitions, located in the submillimeter range. In addition, it could be possible to find several rotational lines of the SiS isotopologues displaying maser emission. Comment: 4 pages, 1 ...
quantum number n. Thus, the designation "2p" indicates a level that has L equal to 1 and n equal to 2. In order to observe the Zeeman splitting, the Zeeman effect experiment needs to be carried out. This splitting of spectral lines under the magnetic field is also known as Zeeman ...
Spectral observations are also reported for L1551/HH-29. Analysis of the variation of gas kinetic temperature around several of the mapped sources shows close agreement with the expected grain kinetic temperature, assuming these sources to be irradiated by single central stars of a spectral class ...
