Original Abstract

The presented comparative study is focused on diatomic nitrogen which comprises on average 78% main part of the atmosphere. Spectroscopic properties of nitrogen include individual states and transitions among them and play an important role in the Earth's protection against highly energetic vacuum ultraviolet (VUV) and extreme ultraviolet (XUV) radiation. The comparative study focuses on the band of transitions between the A3-B3 states. Its uniqueness lies in that it covers a gap in the scientific literature regarding spectral intensity comparisons for the entire band of currently known transitions between A3-B3 states of diatomic nitrogen. In the introduction, the work deals with the content of spectroscopic data on the A3-B3 band in some publicly available world databases. It showed that the initial collections of spectroscopic data on this band were not a common standard of scientific databases. Due to the complexity of calculating spectral intensities, it was necessary to draw input data on this band from multiple sources. For the purposes of the calculation, the open-source spectra calculation program Lino da Silva's SPARK is used. The calculation procedure of which is documented by the given relationships. The compared spectra form 3x10^5 intensities. For the needs of comparison of the spectra, the author of the study supplemented the existing program with a program sequence in the MATLAB environment. It allowed working with an adaptive grid and creating a histogram. The resulting comparison showed that in the places of the spectra with the greatest intensity, their difference was an average of 27%. Overall from the histogram, only 10% of the mutual deviations ranged between 60 to 80%. In conclusion, some possible causes of errors and their sizes are discussed.
