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.

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.

The emission spectrum of protactinium in the 0·8–3·0 μ region

Spectrochimica Acta, 1963
The emission spectrum of Pa/sup 231/ from an electrodeless discharge tube was observed in the region of 0.8 to 3.0 mu . Wavelengths and intensities were measured for about 1200 lines, many of which show hyperfine structure. (auth)

The role of adsorbates in the Na+-induced kinetic emission of electrons from Ru(0 0 0 1)

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2002
Abstract Electron emission was measured from clean and adsorbate-covered Ru(0 0 0 1) surfaces under bombardment by 120–1620 eV Na + ions. A kinetic process is solely responsible for the emission of electrons in these systems, as the low ionization energy of Na excludes any potential emission.
