Calculations were made of the volume and integral emission intensities of the Lyman–Birge–Hopfield (LBH) bands of molecular nitrogen at 146.4, 138.4, 135.4, and 132.5 nm in the upper atmosphere of Titan during the precipitation of electrons with energies of 30–1000 eV from the magnetosphere of Saturn, taking into account the kinetic processes for singlet excited states of N2 molecules. Calculations showed that the ratios of the calculated integral emission intensities of the LBH bands to the emission intensity of the 337-nm band of the second positive system for the entire interval of the considered energies of magnetospheric electrons take on constant values. The results obtained are in good agreement with the calculations performed for auroral electrons precipitating into the Earth’s polar ionosphere.
