Important lines are the hydrogen Balmer lines, lines of neutral and singly ionized helium, iron lines, the H and K doublet of ionized calcium at and nm, the G band due to the CH molecule, the nm neutral calcium line, several metal lines around nm, and the lines of titanium oxide. Compound ZIRCONIUM(IV) OXIDE with free spectra: 2 FTIR and 2 Raman.

The lines of singly ionized iron (FeII) are present in absorption and emission in the spectra of objects such as the Sun, cool stars, circumstellar envelopes of hot stars, novae, diffuse nebulae including the supernova remnants, and active galactic nuclei.

OftheanomalousZeemaneffect,wereturnedagaintotheZrspectra. TheZeeman effects observed by Moore 7 were now inter pre table, and, through the kindness of Dr.A. King, of the Mount Wilson Obserya. Two-hundred and twenty-four new atomic zirconium lines are found in the region between and A.
Spectra of unionized and singly ionized zirconium. book are attributed to transitions between previously determined terms of neutral zirconium, Zr i.
One is attributed to known terms of singly ionized zirconium, Zr ii. The emission line spectrum of singly ionized atomic oxygen (O II) dominates the day airglow spectrum in the extreme ultraviolet below Å. The strongest resonance line, at Å, is optically thick and an analysis of height profiles obtained from rocket observations between and km in specific viewing directions indicates that the principal excitation source is direct Cited by: level data for only two spectra Mo I,II of the 72 spectra of the neutral and singly-ionized atoms of the elements Rb to Ba (Z 37–56) and Hf to Ra (Z 72–88).
No complete and critical compilations of energy levels have appeared for most of these spectra since Vols.

Singly ionized helium (He +) is a hydrogen-like ine the energy in eV required to raise a He + electron from the n = 1 to the n = 2 energy level. At these delays, the spectral lines of both neutral and singly ionized species are equally developing, because of presence of local thermodynamic equilibrium.
Thus, results corresponding to this range of gate delays should be most correct – molybdenum (– at.%), titanium ( – at.%) and zirconium (– at.%). The appearance of singly ionized iron emission lines in the spectra of early type stars is studied, and the results of a spectroscopic investigation of EW Lac and other Be stars are given.
We also discuss the atomic processes of excitation of Fe ti in the stellar envelopes using a two-parameter diagram W, N.
We report new observations of the spectrum of singly ionized chromium (Cr II) in the region Å. The spectra were recorded with the National Institute of Standards and Technology m.
The spectrum of neutral and singly ionized magnesium produced by a hollow-cathode discharge has been observed by the Fourier transform spectroscopy technique between and cmThe observations reported here have allowed an extension of the term systems of Mg I and Mg II; more particularly, first observational evidence is reported for 3s ng 1,3 G(n ≤ 8) terms of Mg I and ni 2.
 We present middle ultraviolet spectra between and Å showing emissions due to singly ionized iron and magnesium. The spectra were observed by the Ionospheric Spectroscopy and Atmospheric Chemistry (ISAAC) instrument on the United States Air Force's Advanced Research and Global Observing Satellite (ARGOS).The emission from ionized magnesium has been previously.
The spectrum of singly ionized iron, Fe II, has been recorded in the wavelength regions Å and Å by means of a pulsed hollow-cathode discharge. In the vacuum-ultraviolet region identifications are given for lines. The list for the region above Å contains observed lines, of which are identified.
The spectrum of Zr vi has been observed in a sliding-spark discharge with a 5-m grazing-incidence spectrograph. The analysis has yielded nearly all levels of the 4p44d configuration that can combine with the 4p52P ground term.
All of the 4p45s levels as given by Chaghtai were confirmed. The 4s24p44d+4s24p45s+4s4p6 level structure has been theoretically interpreted, with configuration. Harold T.

Wang et al. suggested that this higher energy PL shoulder originate from the transition to singly ionized associated oxygen vacancy defects (referred to as AOD + centers). The energy levels and observed spectral lines of neutral and singly ionized titanium atoms have been compiled.

Their detection is only possible under very favourable conditions with the most sensitive schumannised plates. Strong spectral lines in the visible part of the spectrum often have a unique Fraunhofer line designation, such as K for a line at nm emerging from singly-ionized Ca +, though some of the Fraunhofer "lines" are blends of multiple lines from several different other cases the lines are designated according to the level of ionization by adding a Roman numeral to the designation.
