Analysis of the first triad of interacting states (0 2 0), (1 0 0), and (0 0 1) of D216O from hot emission spectra

Journal of Molecular Spectroscopy, 2005
Abstract The far-infrared and middle-infrared emission spectra of deuterated water vapour were measured at temperatures 1370, 1520, and 1940 K in the ranges 320–860 and 1750–3400 cm−1. The measurements were performed in an alumina cell with an effective length of hot gas of about 50 cm.

Hot water emission spectra: Rotational energy levels of the (0 0 0) and (0 1 0) states of HD17O

Journal of Molecular Spectroscopy, 2015
Abstract The rotational transitions of the HD17O water isotopologue have been assigned in a high temperature emission spectrum between 320 and 520 cm−1 of water vapor enriched by deuterium and 17O. We assigned 169 emission lines to 189 partly overlapping transitions of pure rotational and the ν2–ν2 rotational bands.

b1Σ+ Emissions from group V–VII diatomic molecules. b 0+ → X1 0+, X2 1 emissions of AsI and SbI

Chemical Physics Letters, 1984
Abstract Chemiluminescence from the b 0 + → X 1 0 + band system of AsI and of the b 0 + → X 1 0 + , X 2 1 systems of SbI in the near-infrared spectral region has been observed in a discharge flow system. Analysis of the spectra led to the spectroscopic constants (in cm −1 ) of AsI: ω e (X 1 , X 2 ) = 257 ± 2, ω e x e (X 1 , X 2 ) = 0.82 ± 0.2,

Spectral analysis of the low energy Auger emission from a (0 0 0 1) ruthenium surface

Applied Surface Science, 2003
Abstract The low energy Auger emission from a Ru(0 0 0 1) surface have been analysed by means of a cylindrical mirror analyser (CMA) within the range of the electron energy ( E ) from 27 to 37 eV as a function of the primary electron energy ( E p ), which was set from 170 to 450 eV in 20 eV steps. Three Auger transitions at following energies: 31.7,

Otoacoustic Emissions and Tympanometry Screening Among 0–5 Year Olds

The Laryngoscope, 2002
AbstractObjectives To determine the rate of otitis media (OM)‐associated transient evoked otoacoustic emissions (TEOAE) screening failure in a sample of preschool children, to evaluate concordance between TEOAE and tympanometry, to investigate risk factors for TEOAE failure, and to determine agreement between TEOAE failure and physician findings at ...

Absorption and Emission Spectrum of [Zn₄0(Acetate)₆]

1990
The electronic spectrum of [Zn4O(acetate)6] in solution is characterized by an absorption (λmax.= 216 nm) and emission (λmax.= 372 nm) band; it is assigned to a ligand-to-metal charge-transfer (LMCT) transition, which corresponds to the band-gap transition of the semiconductor ZnO.
