Once you are proficient at analyzing the absorption lines
of stars, you might try examining the emission lines of nebulae.
When the emitting wavelength of the DFB driver has been stabilized to the absorption peak of gas, a saw tooth wave signal [u.sub.saw](0 = [A.sub.saw] + ([A.sub.saw]/[T.sub.saw]) (t - [T.sub.saw]) is generated to tune the central wavelength to scan the absorption line
This can be explained as follows: for two-hour dispersion of suspension there is no destruction of adsorption-solvate layer, i.e., carboxymethyl cellulose from the surface of carbon nanotubes, but with the prolonged C-O bond of carboxymethyl cellulose is broken, so the absorption line
The strength of the emission lines decreases and absorption lines
of singly ionized metals get stronger from 2010 to 2013.
Because we do not know the distance and temperature of the X-ray absorbing cloud and the degree of ionization of the oxygen atoms, the exact wavelengths of the absorption lines
are not known a priori.
where [[alpha].sub.i,j] = [A.sub.CUT.j]/[A.sub.ref,i] and [[beta].sub.i,j] = ([MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII]) * ([p.sub.CUT,j]/[p.sub.ref,i]), and to the premise that the same spectral feature, that is, the same molecular absorption line
of the strength S, was probed in both cells.
It was taken into account, that the curve must cross the origin of co-ordinate system because if there is no CO, absorption line
height is equal to 0.
The laser wavelength was tuned to 894 nm which is equal the cesium D1 absorption line
F = 4 [right arrow] F = 3 transition and stabilized using saturation spectroscopy in an auxiliary cell.
When analyzing the effects of the real exchange rate appreciation in the framework of the Salter-Swan-Meade diagram in Figure 2, turn the absorption line
(A) and the income line (S) to the right (to A' and S', respectively) so they become more steep.
During absorption measurements, the AOTF increases the signal-to-noise ratio by restricting radiation from the atmosphere to a narrow spectral range of approximately 10 |cm.sup.-1~ around the absorption line
. The AOTF is operated from 3.5 to 14 |micro|meter~~ during emission measurements.
The emission line shows large variation in its interferogram while they fade quickly for the absorption line
. In this example, only a [square root of N] photon noise is applied and, since the mean flux is the same for both lines, the average level of noise is about the same.
The intensity [S.sup.B.sub.A] in [cm.sup.-1]/(cm atm) of an individual absorption line
with frequency [v.sub.AB] in [cm.sup.-1] is given by :
