Abstract :	[en] Eight spectrograms of Comet 19481, covering the range of heliocentric distances from 0.65 to 2.21 A.U., have been obtained. Sodium emission is observed at r = 0.73 and r = 0.79 A.U. At large heliocentric distances (r = 2.21) only CN and the λ 4050 group are observed. The CN bands show the usual complex structure due to the fluorescence excitation by solar radiation. The behavior of CH and that of CH2 are compared. Unidentified features are present within and between the Swan bands, as well as in the yellow-red region.
