Populations of rotational levels of molecules in clouds with large red shift

The influence of the field of the microwave background on the populations of the rotational levels of CO molecules in molecular clouds of galaxies with large red shifts is studied. The regions of kinetic temperatures and gas concentrations typical of molecular clouds of the Galaxy are considered. Th...

Zusammenfassung:The influence of the field of the microwave background on the populations of the rotational levels of CO molecules in molecular clouds of galaxies with large red shifts is studied. The regions of kinetic temperatures and gas concentrations typical of molecular clouds of the Galaxy are considered. The influence of the field of the microwave background is investigated for red shifts in the range of 1-s. (Author)
