Fluorescence efficiencies of electrons in molecular nitrogen and oxygen gases

Abstract

Fluorescence efficiencies of electrons in a large number of bands of the N 2 First Positive and O 2 + First Negative groups lying in the 4900–10,500 Å wavelength range have been investigated theoretically. The variation of transition moment with internuclear distance is taken into consideration. For the First Positive group of N 2 the calculations are carried out at very low pressure as well as at 600 Torr. In general the present values are higher than the experimental values but in most of the cases fair agreement has been obtained. For the O 2 + First Negative group no direct experimental data is available. However, the present ratio of the total efficiency in the O 2 + First Negative group to the N 2 + First Negative group is found to be in good agreement with the experimental intensity ratio.
