The analysis of radiation associated with electronic vibrational-rotational (EVR) transitions in molecules of hydrogen isotopes is very informative for studying processes in the tokamak edge plasma. Emission spectra together with atomic lines are represented by a set of overlapping molecular bands with a pronounced rotational structure. The identification of the rotational lines of the spectrum is a very laborious task that is complicated by the overlapping of numerous vibrational bands, which requires the analysis of a huge number of EVR transitions. The computer recognition of the spectrum and its use for the determination of plasma characteristics are complicated, since there is no digital atlas of radiative transitions for hydrogen isotope molecules. The digital atlas created by the authors on the basis of available literature sources and described in this paper contains information on more than 57 electronic transitions and 7000 lines for deuterium molecules, as well as 69 electronic transitions and 13 400 lines for protium. The atlas contains not only the wavelengths and corresponding energies but also the constants necessary for calculations (vibrational and rotational quantum numbers, tabular intensities, branch type, etc.). The atlas was created to be published on the Internet as a public digital resource. It is implemented as a Web site which will be hosted on a server of one of the organizations involved in atlas development. In order to provide the possibility of using the atlas to interested users from other countries, all its interfaces are made in English.
