Abstract

New set of wavenumber values for electronic-vibro-rotational (rovibronic) transitions in limited part of the emission spectrum of the D₂ 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 D₂ spectral lines has been observed in the visible part of the spectrum.
