New set of experimental wavenumber values for visible part of emission spectrum ($545÷627$ nm) of the $D_2$ molecule with partly resolved fine structure of triplet-triplet rovibronic transitions

Abstract

New set of wavenumber values for electronic-vibro-rotational (rovibronic) transitions in limited part of the emission spectrum of the $D_2$ molecule ($545÷627$ nm) have been measured with a precision $0.007÷0.1$ cm${}^{-1}$ depending on the translational temperature in plasma, the signal-to-noise ratio, and the degree of overlap with adjacent spectral lines. For the first time partly resolved fine structure of the $D_2$ spectral lines has been observed in the visible part of the spectrum.
