Calculation of intensities of torsional-rotational bands in the IR absorption spectrum of hydrogen peroxide

“…Research of the last decades has shown convincingly that very simple peroxides and their fragments that are present in trace quantities in the upper layers of the atmosphere have a destructive effect on the ozone layer of the earth [12,16]. Therefore, the study of the spectral characteristics of these compounds is of great interest.Energy states, frequencies of torsional and torsional-rotational transitions, and group theory approaches to establishing selection rules in IR and Raman spectra have been calculated several times [4,5,7,8,[17][18][19][20]. Nevertheless, intensities of rotational components of torsional transitions of hydrogen peroxide in the far IR region have not been calculated.…”
