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

Abstract

The visible part ($\approx 419-696$ nm) of the multiline electronic-vibro-rotational emission spectrum of the $D_2$ molecule was recorded with moderate resolution mainly limited by Doppler broadening of spectral lines (line widths FWHM less than $0.013$ nm). After numerical deconvolution of the recorded intensity distributions and proper calibration of the spectrometer the new set of wavenumber values was obtained. It is shown that new data are significantly more precise than those available for visible part of the $D_2$ spectrum. Final results are reported as a supplement in the form 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, intensity distributions in linear and logarithmic scales and the table containing wavenumber and relative intensity values for 11941 spectral lines together with available and new line assignments for the $D_2$ and $HD$ molecules.
