Swings, P. ; Page, Thornton Abstract The spectrum of Comet 1947n has been observed from heliocentric distance r = 0.504 to r = 1.135 between X 3000 and X 8900. The OH band is unusually weak relative to NH. The (0, 0) band of CN reveals a complex rotational structure due to fluorescence, similar to that observed in previous comets. Features appearing within the Swan bands are described and discussed. The red region is mainly due to NH2. Two intense infrared emissions have been found for the first time at X 7906 and X 8106. A de- tailed discussion seems to indicate that they may be attributed to the red system of CN. This CN emis- sion in the infrared does not result from fluorescence but probably from the photodissociation of a parent- molecule. No atomic lines have been found other than the D lines of Na. The two components of the nucleus reveal exactly the same spectrum Publication: The Astrophysical Journal Pub Date: November 1948 DOI: 10.1086/145091 Bibcode: 1948ApJ...108..526S full text sources ADS |
