摘要: Abstract The forbidden NI ( 4 S° 3 2 − D° 5 , ) transitions are shown to be a permanent feature of the upper atmosphere at night. This determination was made with Fabry-Perot spectrometer large luminosity-resolution product capable resolving these transitions. temporal behaviour this emission also measured and can explained in terms ionospheric reactions, electron quenching, molecular oxygen quenching. A value 2−1+2 × 10−4 sec−1 for frequency quenching by 230 km derived from measurements.
