Twilight transition spectra of atmospheric O2 Ir emissions
Abstract
Resolved spectra have been obtained from the ground of the O2(a¹Δg) emissions from the upper atmosphere utilizing a wide-field interferometer with a cryogenically cooled germanium detector. The rotational structure of both the (0, 0) band at 1.27 µm and the (0, 1) band at 1.58 µm are clearly separable from the hydroxyl airglow. The decay rate of the O2(a¹Δg) during the twilight transition has been observed.
