(PDF) Night-sky spectral atlas of OH emission lines in the near-infrared
The potential of night-sky emission lines recorded on every long-exposure astronomical spectrum, for wavelength calibration, is emphasized.
Jun 26, 2009 an atlas of the spectrum of a platinum/neon hollow-cathode reference lamp in the region 1130 å to 4330 å is given, with the spectral lines marked.
This report records the prominent lines of the icp emission spectra of some 70 elements as the first step in the development of a spectral atlas that would serve.
Commercial or mixed xylene usually contains about 40-65% m-xylene and up to 20% each of o-xylene and p-xylene and ethylbenzene. Xylenes are released into the atmosphere as fugitive emissions from industrial sources, from auto exhaust, and through volatilization from their use as solvents.
Full wavelength-calibration of spectra using night-sky emission lines here are two coarse maps which i have made of a sky spectrum i obtained my list of sky line wavelengths (which currently covers mostly 7840 å to 9570 å but will.

The figure below shows the atomic emission spectrum of hydrogen. The set of individual colors emitted by an element is called its spectrum.
The hubble space telescope (hst) is a space-based great observatory providing spectroscopy and high-resolution imaging at uv, optical, and near-infrared wavelengths.
Respiration is the most likely route by which 2,2,4-trimethylpentane is absorbed. Although it has not been determined, the respiratory uptake of 2,2,4-trimethylpentane is probably similar to that seen for n-octane.
