electronic spectrum

electronic spectrum

[i‚lek′trän·ik ′spek·trəm]
(spectroscopy)
Spectrum resulting from emission or absorption of electromagnetic radiation during changes in the electron configuration of atoms, ions, or molecules, as opposed to vibrational, rotational, fine-structure, or hyperfine spectra.

The Director General, during his briefing, reiterated that operating a press or a medium in the country is free, however, 'it is only when you are using an electronic spectrum and frequency that you apply to the NCA to give you the license and band to stay alive.'
For almost two decades, Celtronic has showcased the biggest names from across the electronic spectrum alongside the best DJs, producers and live acts from the local Irish scene.
Table-1: Electronic spectrum and electron transitions for EBT-M complexes in magnetized and non-magnetized water.
Formal military terminology defines electronic warfare (EW) as a military action to control the electronic spectrum, says De Martino, and this objective is achieved through offensive electronic attack, defensive electronic protection, and intelligence gathering and threat recognition support actions.
The electronic spectrum of the aqueous solution of free ligand showed absorption bands in the UV-region at 228 nm (43, 860 [cm.sup.-1]), 240 nm (41, 667 [cm.sup.-1]) and 307 nm (32, 573 [cm.sup.-1]).
In the electronic spectrum of unimetallic complex, a strong band is observed at 589 nm, which is due to d-d transitions, and is a characteristic feature of the square planar complexes while a strong band at 297 nm and shoulders arise due to the intraligand transitions [26].
The electronic spectrum of furan Schiff base ligand (H-MFMAQ) in ethanol exhibited five absorption bands (Figure 2(a)) at 233-338 nm regions which is due to [pi] [right arrow] [[pi].sup.*] and n [right arrow] [[pi].sup.*] transitions utilizing molecular orbital of the quinoline and furan rings, C=N and C=O groups.
Throughout, there is one common theme: The electronic spectrum through which communications are transmitted has not, in and of itself, physically constrained growth and expansion of telecommunications, although that is a popular justification for federal regulation.
Expect music from across the electronic spectrum from deep house, progressive, future house and big room with DJs Connor Jones, Audio-Force, Adam Bowman, Duane Makin, Drew Mooney and, Max Muscatelli playing back to back with Reece Normo.
Strategic and tactical operations require electronic spectrum domination to assure mission accomplishment.
At ALS beamline 10.0.1, the collaborators determined the electronic structure of their material using Angle-Resolved Photoemission Spectroscopy (ARPES), in which x-rays striking a material surface or interface cause the photoemission of electrons at angles and kinetic energies that can be measured to obtain a detailed electronic spectrum. Sodium bismuthate is too unstable to be used in devices without proper packaging, but it triggers the exploration for the development of other 3DTDS materials more suitable for everyday devices, a search that is already underway.
It has been found that heating indeed influences the electronic spectrum, although the changes upon heating to ~80[degrees]C are modest.
