| Abstract: | Absolute spectrophotometry of the coma of Comet Kohoutek 1973f is discussed for the nights of January 24 and 26, 1974. Specific intensities are measured for spectral features and a continuum band in the wavelength region λλ3460–6062Å. The (0, 0) band of the Δν = 0 sequence of the violet system of the cyanogen molecule is analyzed and column densities of 1.7 × 1015m?2 and 3.4 × 1014m?2 are found for January 24 and 26, 1974, respectively. The analysis of the bands of C2 will be reported in a second paper of this series. |
