Atlas and wavenumber tables for visible part of the multiline electronic-vibro-rotational emission spectrum of the $D_2$ molecule measured with moderate resolution in deuterium plasma with minor hydrogen impurity

摘要

The visible part ($\approx 419-696$ nm) of the multilineelectronic-vibro-rotational emission spectrum of the $D_2$ molecule wasrecorded with moderate resolution mainly limited by Doppler broadening ofspectral lines (line widths FWHM less than $0.013$ nm). After numericaldeconvolution of the recorded intensity distributions and proper calibration ofthe spectrometer the new set of wavenumber values was obtained. It is shownthat new data are significantly more precise than those available for visiblepart of the $D_2$ spectrum. Final results are reported as a supplement in theform of an atlas divided into 158 sections (each section covers about 1.5 nm)containing pictures of images in the focal plane of the spectrometer, intensitydistributions in linear and logarithmic scales and the table containingwavenumber and relative intensity values for 11941 spectral lines together withavailable and new line assignments for the $D_2$ and $HD$ molecules.
