red shift

or red·shift (rĕd′shĭft′)
An increase in the wavelength of radiation emitted by a receding celestial object as a consequence of the Doppler effect.

[From the fact that the longer wavelengths of light are at the red end of the visible spectrum.]

(Astronomy) a shift in the lines of the spectrum of an astronomical object towards a longer wavelength (the red end of an optical spectrum), relative to the wavelength of these lines in the terrestrial spectrum, usually as a result of the Doppler effect caused by the recession of the object. Compare: blueshift

Thus, analysis of structural, electronic and, principally vibrational parameters, using DFT hybrid functionals, may produce satisfactory results, not only for red-shift interactions, but also for the blue-shift hydrogen-bond type.
Comets are represented by two paragraphs and Red-Shift demonstrations of Comet Shoemaker-Levy 9 smacking into Jupiter and the orbit of Halley's Comet.
What's more, because cluster galaxies have a fairly well specified range of intrinsic brightnesses, a cluster's apparent brightness range can crudely reveal its red-shift. The Palomar cluster redshifts reach out as far as 1.1 - implying distances of 5 to 8 billion light-years.
The ZITs refer to an interesting time, ascosmologists describe it, back at a red-shift of 1,000.
A dip at 6545 angstroms suggests that the quasar's light is being selectively blocked by a massive intervening hydrogen cloud at a lower red-shift of 4.38.
For instance, the quasarlike object Markarian 205 (red-shift 0.07), which is very close to the redshift-0.0057 galaxy, NGC 4319 in Draco, is itself apparently connected to three quasars of much higher redshift (0.464, 0.633 and 1.259).
A lot of atomic charge algorithms have been used in the comprehension of the red-shift phenomenon, e.g., the Mulliken charges [130-131], the Bader partition [132] supported by the formalism of the Quantum Theory of Atoms in Molecules (QTAIM) [133], Charges from a Electrostatic Potentials using a Grid-Based (ChElPG) [134], or even the Natural Bond Orbitals (NBO) [135].
The red-shift of the absorption band is due to the extended I-conjugation framework of SDPP-PPV vs.
Figure 1 shows how the self-steepening effect influences the red-shift DW generation; here the positive TOD ([[delta].sub.3] = 0.0267) is considered.
The peak position maps of A excitons in Figure 3(c) show the significant red-shift of A exciton peak by ~16 nm in the DNA-stretched 1L-Mo[S.sub.2].
Trinity, FL, April 07, 2014 --( Bayramov's research in his new book - "Mechanics of Natural Force" - Flow Theory of Matter and Gravity argues that the cosmic red-shift is not caused by receding stars but by stellar gravitational flows, and shows that star-light coming from a remote star propagates asymmetrically through the gravitational flow of a local star.
